I have (had) two friends who did much the same thing to me - one I grew up with and another I had known for fifteen years. Both are gun owners and claim to be both pro-RKBA and pro-CCW. During the years of the Missouri CCW battles they both cried about how unfair it was that the legislators would not pass the law. When it looked as though the law would finally pass - they both seemed as delighted as I was - and they both insisted they would be getting their licenses. When I actually DID get my License to Carry - both of them made it clear they did not want me carrying around them. This was in spite of the fact that my family was and still is being stalked and harassed by a violent speed-freak.
Do they fear me? Do they envy me? Do they resent the fact that I actually did what I said I would do? I don't know and really don't care anymore. I am NOT going to put myself and my family at risk just to be in the company of a so-called "friend" who does not trust me and believes I DON'T have the right/responsibility to defend myself and my family.
As for leaving the church - keep in mind that old saying; 'Bad things happen when good people do nothing'. If good people leave the church because of the things the pseudo-Christians do there - who does that leave?
