Tone is everything when you're trying to get your point across and want people to listen and understand. I'm not going to go searching through your conversations with other people when I'm talking to you.
For what it's worth, if there were any cause for suspicion, then sure. But some of us have been here a lot longer than you and at this point, all that's come in are the people who take residence here. The potential for threat, is on the other side of the doors. If you were going from a standpoint of suggesting maybe it might be a better idea for people to go through them in groups, I could get behind that. But what you're suggesting, even if it's not about people (which I don't see how it can be -- what you're suggesting is about threats coming through alleged weak points but they easily could just be a new citizen popping up here without incident), sounds like paranoia at best.
