"I am tempted to start carrying my sidearm (legally of course), I am not taking any more c*** from these people."

This sentence makes clear that you would be looking for a reason to use that sidearm, either to threaten or actually shoot if things escalated. Your a hothead looking for trouble and you may get it. I can be a hothead sometimes too, which is why despite owning firearms, I won't carry them in public. The risk to myself( and others) is too high.
