I never see the Bahai or Muslims come after each other's beliefs..
This thread with recent entries goes into some detail about the active persecution of Bahai by Muslims, or at least by the Iranian Government.
I don't think it says as much about the intricacy and ferocity of their doctrinal disputes. Only that Bahai are seen as apostate by Islam. They are denied freedom and within the long persecution history there has been jailing, executions, exile, marginalization, disenfranchisement etc.
There are some pretty significant splits within Islam, too, which also lead to fights and abuse. The divisions I think are based in doctrinal disputes, so definitely going after each other's beliefs within Islam, how to interpret passages of the Koran and how people should live, etc, but I am afraid I don't know much about them other than their existence and their severity.
Probably not, see below
Does my faith offend them?
In simple terms, the teachings might. Or some evangelists have.
In long winded terms, see below.
In my experience talking to I don't know how many people over the years and decades, and during the same stretch of time observing numerous people react to street evangelism, and reading I don't know how many blogs: Many people are offended by many things about many religions. Many people ignore many things about many religions. (Including their own) The most consistent thing to pop up (and something I also find troubling and doubtful) as a "worst offender" is the teaching in most branches of Christianity and - many? branches of Islam, that anyone who is NOT a believer of that faith will have an afterlife and go to eternal conscious torment in some kind of hellfire. Or at the very least, many people BELIEVE that most prominent branches of Christianity and Islam teach this doctrine for nonbelievers/infidels.
It's not a surprise or secret why people would be offended. ("How dare those evangelists who don't know me say such rubbish to me!") And if they thought it was true they might feel God offended them, sure, by inventing hell and having such a policy... but that's only rarely where it goes in my observation.
Those who take what they hear to heart and ponder it and consider it are troubled, anyway.
Many brush it off with a scowl or outright ignore these teachings as only absurd.
Some who are both rattled and confused by evangelism eventually defy the offensive teachings by examining scripture themselves and finding support limited or wanting (for the afterlife doctrine or any number of teachings evangelists try to sell them) and start their own denominations that present, say, conditional immortality. (In Christianity anyway. I know less about the organizational or doctrinal divisions in Islam)
Those dissenting denominations, like Christadelphians, SDAs, Armstrong variants, JWs etc, or spinoffs like Mormons, are generally fundamentalist and hardliners in their own way, and also offend many, not the least of which are the mainstream Christian followers they defy.
Jews are often not subtle in expressing their unhappiness with Christian (or Mormon) evangelism--both its content and its energetic persistence. As I currently understand it, in the view of many Jews, it is not God who offended them at all, but the Christian or Mormon evangelism and the message they believe to be inapplicable to them at best, outright wrong on an average day, and blatant apostasy at worst.
They are no more delighted with the message of Islam AFAIK.
Closer to our recent debates on the forum: I don't know the overall position that other religions such as Bahai, or Rasti, or anything else in the Abrahamic family take towards the teachings of Christianity (or Islam) nor their idea of what an interfaith relationship with Christians (or Muslims) should look like. I know even less about what various Eastern faiths would say their official "take" on Christianity or other Abrahamic faiths would be. It doesn't come as any surprise really, though, at some "family squabbling" amongst members of the various Abrahamic sects. It's not about thinking the same God they all officially worship is offending them. It's more about sibling rivalry. I am not sure how many Abrahamic faiths there are, 7 or 8? maybe more? What a family! What an opportunity to say look at me, I'm the best, you stink, etc. Traditional Christianity and Islam receiving the hardest pokes from younger sibs because of the perceived hardness of their afterlife doctrine and their claims of exclusivity. (i.e believe it or else, or at least Christianity and Islam are often
perceived as saying, believe us or else)
And of course, scientific minded rationalist-materialist non believers in at least in much of the West seem to appear to reserve their defiance for Christianity due to its dominance/pervasiveness/familiarity. Their main objections are to the aboslute truth claims. It's not that God offends them, that's not possible for they who do not believe. Evangelists (whom the rationalist-materialist scientistic sorts think are preaching make believe) offend their "take" on reality and reason. To hear some modern debates between believers and scientistic non believers, you could almost get the impression that there were only two world views in the whole wide world, Evangelical Christianity and hard scientism. And of course they don't like each other. But no one else need apply. In that dichotomy, no one else exists.
But yes, if they're offended, it's by what they see as an illogical/irrational rejection of scientific discoveries on the part of evangelical hardliners.
And nobody else with more subtle, metaphorical, or reasonable views even exist, or they don't notice them.
Everything is black and white or either or. (Nuanced debates don't get as good press)
