No you would not, jomifl. Depending on the circumstances you would be prosecuted for a religiously aggravated offence, not a racially aggravated one. A mute point because the penalties are usually the same, but an important one for the sake of this question. It's interesting, though, that you should mention that "...most muslims are born into islam and cannot opt out". I think a bit part of Islam's problem is that children are born into its faith and cannot make up their own minds about it later in life (presumably for fear of violent retribution).
I'll not go down the road of arguing why criticising a religion is not racist, ZebUK (but see above).
I know you seem to have opted out of a debate in which you freely took part. I imagine you did not like some of the opinions voiced. But, in case you have not, I will defend your accusation that I am an ignorant excuse for a human being. I've been accused of many things, but ignorance is not usually among them. I am perfectly well aware that there are multifarious strains of Islam. That, my friend, simply compounds the problem because it seems that not only can many (not all, remember) Muslims not tolerate other religions, they also cannot tolerate different strains of their own. (Bear in mind that, bar the Israel/Palestine/Gaza scuffle, strife in the Middle East and much of Africa is almost entirely due to "tribal" disagreements between the various Islamic factions). I will defend my description of Islam as wretched because whilst it has many peaceful and peace loving followers, it has a hugely disproportionate number of followers prepared to cause death, destruction and mayhem in the name of their cause. That's why I describe it as "wretched"
It is interesting that Bravehearted suggests that religion is the root of all evils. I don't know about all evils but in one way or another religion is certainly responsible for just about all of the world's wars. Today it is Islam, tomorrow it will be something else.
