This is an interesting topic and discussion.
Your problem is you have no faith.
One should have faith in God. If I had no faith I would not go to place of worship in the first place. Guns in place of worship are inapropriate.
. I feel 100% safe in place of worship w/o being armed.
Except for all of this nonsense ^^^^^^^^^^^. Assuming people have no faith because they do something different then you is totally inappropriate and down right rude. Advocating people abandon their means of defense because YOU feel one way is dangerous. If you feel 100% safe in church, that's good for you, but your assertions are just as socialistic and suppressive of people's personal rights as all the gun grabbers and banners out there. Do you also advocate gun free zones? You know, like the ones that keep getting shot up?
Remember the Sikh temple shooting in Oak Creek, WI like 6 or 7 years ago? Then there was the racially motivated shooting in that Baptist church in Georgia, I think 3 or 4 years ago. Churches are vulnerable just like any other location. When people with murderous intent start getting fried at the door by unexplained lightning on sunny days, THEN we can all feel safe. Until then, I'm going to carry on. Do what you like, that's your right, but I completely disagree with everything you said.
@bluejeans I used to run the sound board for my girl friend's church for 2.5 years. It was a trans-denominational church, and really did bring in some misfits, lost souls, people with personal problems, etc. I called it a hippy church, though I mean nothing derogatory about that. I like lots of and work with lots of modern day hippies. Anyway, the married couple that ran the church let anyone in, and welcomed everyone. It's a nice thing to do, but they were also letting drug addicts and homeless people stay there. I carried every time I attended and ran the board. I was in a booth, which gave me an excuse to sit in back, and keep an eye on the door., and also gave me some cover. But I and the pastor were basically the only ones who faced the entryway. I waved hello and said hi to anyone who came in, but kept my distance. I also got in the habit of shaking hands with my left hand the first few times I met someone, until I was at least a little comfortable that they weren't a threat. It confused people because most people expect a right hand. None the less, it left my strong arm free to shove someone off me if they tried anything, and then draw. One creepy dude in general, who exhibited clear mental fixations on someone and severe psychological issues really bugged me out whenever he'd attend. His behavior was totally inappropriate in any church. Then one day he stopped showing up. I was basically waiting for him to show up one day with a gun and start shooting.
It may seem unfriendly but actively looking for reasons to engage, but not get too close, is a constant and difficult mental workout in these scenarios. Off hand handshakes can help in some scenarios, but not others. I usually only make it a habit to shake new coworkers hands. That's all.
Best bet, be verbally friendly, but look busy when ever you can so you can keep folks at arm's length.
