Hap, you can't hold peaceful people responsible for what extremists do who refer to their own religion by the same name.
Bigotry comes from categorizing people unfairly into classifications that do not befit them. A spiritual teacher who has a past history of peaceful actions is not acting on behalf of any terrorist anywhere, and his desire to build a temple of worship on the same ground he's always used should never be in question - especially in a country like ours who prides itself on religious tolerence.
So why the controversy, Hap? Why would you want the government to interfere with this person, who should have every right to do with his property whatever he wants. Within reason, of course, but we're not talking about him building a momument to the terrorists. He has his own version of the Islamic faith that is very compatible with other peaceful religions in the U.S.
He has never advocated for the mistreatment of women, he has never advocated against Americans or American allies, and he does not support the same views as Islamic extremists.
For you to deny him his place of worship is to have the same level of intolerence that you proclaim comes from the extremists in the Middle East. I'd have hoped to see our country avoid sinking to that level, but the anti-mosque crowd is following the very same patterns as the extremist bigots in the Middle East.
