That is awesome. Whether he is right, wrong or indifferent. I'd rather live in a narrowed minded USA than a pussificated USA.
He can lose his instructor credentials for that actually I do believe.
He didin't say he wouldn't teach non-Christians, only non-Christian Arabs. I guess it's his right to limit his business just like it's our right to get trained wherever we want.
I wish his shop was near me, I guess I'm a stupid narrow minded bigot also.
I prefer a guy who tells you exactly where he stands to one that stands for nothing. Even if you disagree with him, he doesn't leave you guessing.
