It is very easy. Inspect fruits of the person......Just cause someone claims a name does not mean a thing.Many people use this argument to show how other religions are bad or evil. However Christianity has killed in every continent and acts of genocide were regularly commited by Christians. So how can this religion be peaceful? Now
If a religion teaches something and a person claims it and does just the opposite that shows they are using the name only.
If a religion teaches what that person is doing then you can say that followers of that religion is a certain way.
