This might be true but whether it's true or not, I don't see why liberals are so happy to trumpet it. It actually proves that Islam is terrible if "moderate" Muslims are so easily converted to ISIS ideology.
Uh, no. It's pretty easy to radicalize anyone who is constantly made to be at the receiving end of deep cutting and pervasive discrimination. A community of Muslims whose neighbourhood has been senselessly blown up by an American drone is going to be pretty receptive to the message that the US hates Islam, especially if men like Donald Trump basically come out and say as much. Thus the need for caution. Avoid overkill.
I became sympathetic to gay rights as if gay myself -- once I was gay-bashed. Paradoxically I used the most conservative rationale possible: law and order, without which civil rights and political freedom are meaningless. With the gay-basher I had no means of showing that I am straight. Yes, gay-bashers are loathsome people -- but so are racists, religious bigots, child molesters, wife-beaters, and drug-dealers.
OK, I'm a sissy, but I have no attraction to men. You can probably figure that one out.
There is always something to radicalize anyone -- basically a betrayal of the normal standards of acceptable decency or the denial of human dignity.
