Nothing. In fact I do despise Islam.
I despise all major monotheistic religions with the exception of Pastafarianism. Islam is just doing what Christianity was doing a few centuries ago: mass "conversions" and suppression of internal dissent. As for Hebraism, they didn't get a chance for several reasons. They basically got the wrong end of the stick and never had an army until the 20th century.
I don't despise all or at least not to the same degree. My level of despise is mainly based on the level of radicalism their followers show. All, or most, religions have a reason to exist in its origin but when someone takes some "words" or "guides" to an extreme because of "god's word" then deep shit happens.
Islamist (most) are a clear example of taking it too far... but of course they are not the only ones and there are extremist in EVERY religion even if at a different ratio.
Also polytehists religions are not free from radicalism/extremism, like at all.
