I didn't read all the posts, but my advice for the OP is if you don't want to carry all the time, don't.
It's a right, not an obligation.
I carry when I want to and couldn't care less what anyone else thinks about the subject. Right now I am several thousand miles away from my nearest firearm, I don't have a knife, there are no armed guards and I'll sleep tonight without worry.
