I think if you examine the world historically and the world as it is today, then the answer is a resounding yes. The basis of most of the predominate religions teaches/preaches that anyone who doesn't believe in "insert your god here" the way that "you" do is reason enough to consider them inferior and unworthy of their gods worth and protection. Now, saying that, I have met many people of varying religions who say (to your face anyhow) that their beliefs are their own and that they do not judge or persecute because of another's perspective. Mostly though.... I call BS because I've read their books. If they are devout in their beliefs, then anyone outside of their sects are potentially their enemy.

I honestly think it depends on the individual sects within each religion and just how fanatical they are. Some are more radical and others more open. It seems the really loud ones, though they seem to be smaller groups, are the more radical types that make it seem the rest seem just as bad.

I worked in Saudi Arabia for a year, a long time ago. I can honestly say that everyone was much more polite and unoffended with working with an "infidel".

I travelled in Morocco in 1979 and they told me that they generally hate Christians though the ones who told me that said that they were an exception.

I grew up with a Muslim best friend, however his mother was a white Christian and his father was a sunni muslim, so he was possibly atypical, but I never felt unwelcome in their home or company.

In my experience the primary hateful and intolerant religions are Christianity and Catholicism, Muslim follows close by as a third but the death seekers are not so much as religious as they are intolerant. I have met many others from many aspects especially in the military and they are generally not so hateful even after being hated on or entirely disrespected.

Lots of Jews and Muslims hate each other. It depends on the sect they are from. We have that too. Evangelicals think they are the only ones who are right while lots of people claim the Catholics are not even Christian. Isn't this a bit like "no true Scotsman?"

Muslims are taught in the Quran and other holy scriptures to hate unbelievers, especially Jews.

Jews are taught that they are better than everyone else, but not to hate anyone else.

Generally in South Africa religions are tolerant of each other through their common bond of being religious. atheists are the satan in their midst.

I've not heard any here in Thailand from Hindus, Muslims, or Buddhists. They just mind their own business, as people should.
