It's not just annoying its dangerous to the cause of us conservatives. The "Not my Church" crowd are the people that drive masses of moderates and independants to vote democrat. They are the group that in fact with it's outspoken criticism of anyone they don't agree with spiritually has allowed the Democrats to get so much power. The Democrats can rightfully point at the Republicans and say see those hateful people on the right and those they are pointing at are the "Not my Church" crowd.
I used to have to deal with them a lot, mostly at conventions, when I worked for the Republican Party. Meanest people that I've ever met.
