After 9/11, everyone practicing Islam as a faith was immediately labeled a terrorist. Maybe not everyone, but even I bit into the paranoia for a while. But, like all faiths, it boils down to people. Extremists. They exist in every philosophy, religion, political party, and profession.
Do I blame 9/11 on all Muslims? Heck no. It's a few people who like to live in caves and preach hate instead of tolerance I blame 9/11 on. It's those people we need to be focused on — not the average Joe simply trying to get by day to day who believes in Allah instead of a Christian deity. More power to anyone seeking a bit of guidance now and then.
I do object to extremists seeking to do us harm simply because we don't share their beliefs. I have the same issue with people attacking abortion clinics. I have the same issue with people who choose to disallow marriage for gays and lesbians simply because they don't meet the standard of a traditional family. Hate isn't the answer. Acceptance and compromise are the tools we need instead.
So let the Muslim community have their center two blocks from Ground Zero. Prove to the world that we - as a nation - can move forward from our 9/11 black eye and see beyond the hatred that brought down the Twin Towers. If we can't accept that our nation is full of people with differences, then how are we living up to the standards set by our own Constitution and the ideal embodied by the United States?
