To suggest that being "Islamic" is tantamount to being an Al Qaeda sympathizer is an uneducated, stupid opinion. Once someone makes that leap, I can't really respect their critique of US policy.
I assume you are attacking people who use the term "Islamic" in its real content and compare all Muslims with Al Qaida. If that is the case, then I agree 100% with you. Unless you meant Islamic as "Islamist", in which case, yes, they very well could sympathize with the theology and values behind Al Qaida, if not the group itself.
