Religion is, ultimately, about the individual's relationship with the higher. To dismiss someone's religious complaint because of a supposed leader is to destroy freedom of conscience.
If you had said "Pope" instead of "Islamic leader" it would have been classic WASP anti-Catholic bigotry that JFK faced in when running for president.
[EDIT] changed post to reflect that I don't have any problems against muslims' opinions (half my family is muslim in fact), just their leaders.
Oh, that's a clear indication that you do not understand Islam. Fatwas are only binding on the person who issues them. Same for lesser opinions.
Islam is different. While there are currently a lot of Islamic dictatorships, Islam is the genuine religion of personal choice and freedom.
