"mob persecution of unpopular groups typically only makes them stronger "
"Mob persecution" is going way too far. I meant general disapproval, not rocks through windows. And I disagree it makes them stronger. The example I am thinking of is unemployment, which is pretty looked-down-upon in most western cultures. You're not going to be lynched for being unemployed, but do you proudly admit it at parties? No. That is the kind of "soft pressure" I advocate being placed on the religious, not outright oppression.
"you jump from disagreement [..] to the conclusion that a group is "poisonous" and deserves any kind of random harassment and persecution from the anonymous mob"
Again overstating my claims. Not "any kind of random harrassment and persecution", of course. Instead, fairly mild teasing and a general air of disapproval.
