Ive been thinking about this topic for about a decade and have been finding bigotry not only prevailing but increasing. Ill give some examples. Mind you, you may consider this anecdotal, no problem.
1. Some Muslims have this idea that all who dont believe in the prophet Muhammed are lacking morals. This seems like an arbitrary idea, and I am yet to see some scholarly exegesis of what ever Islamic text that states this as such. I would say even if some text say this directly, it is bigotry and should be avoided because its just nonsense. The same sentiment goes to some Christians. But it could be that Muslims and Christians are so vast in numbers that I encounter them more.
2. Some Atheists think that all theists are just stupid. They think all theists are just uneducated, and in fact, about a decade ago I did notice that there was a uprising in atheistic polemics that all theists are just uneducated. And I have known some ex Christians who became Muslims who have told me that once they became Muslims they noticed that the atheistic idea that all theists are just plain stupid and uneducated increased. But this is not based on a worldwide study of course. I have noticed in this very forum. Sometimes when you present some kind of research, they find the researcher was Christian, the atheist had this idea that since he is Christian its invalid. But hey, they took Newton and Algebra. I think that's hypocritical really.
Its better to put it bluntly. This is bigotry. Unresearched, yes. But what ever the background is, or the level of research finding, it is in my opinion, just bigotry because I personally believe that this kind of thinking is not based on research. Its just an indoctrination of some kind.
What do you think?
