The problem is the way so many muslims are sure to react to this insult, which other religions seem able to shrug off.

1] MANY Muslims? You might like to take a look at a few of These Articles. The majority of Muslims are like the majority of Christians, etc...peaceful, tolerant, and appalled at the hate and assumptions made by such statements as the above.

2] Other religions shrug off "this insult" meaning the idiot in FL? I refer you to another article AND statement by religious leaders from across America HERE. They are not shrugging it off.

Regarding your whole statement, do you suggest that any/all insults should be "shrugged off" by groups who are targeted? By that reasoning, we should not have had a civil rights movement.
