Mmm .. blasphemy laws have often been "hijacked" by various people and creeds.The concept of blaspheming in itself... when one makes anything so sacred that a person who doesn't believe as you is automatically characterized by their words seems ludicrous.
The thing is, that it is possible to be an atheist, without making a noise about it.
Those who make a noise about it, usually have an agenda of destroying a society that has
its values rooted in a belief system.
Similarly, it is possible to have "unusual" sexual preferences .. but those that make a noise
about it want to destroy THOSE values.
In other words, what a majority might consider evil-doing, is being challenged by a minority.
..so many societies have laws to protect their social downfall.
These days, the West in particular, have chosen/ or been forced to abandon their cultural roots,
and are heading into dangerous territory, with society breaking down.
Some politicians even famously claim that there IS no such thing as society!
