Don't click them?
People are trying to help other people out and make threads because of the limited supply of just about everything right now, and the stickied threads get off track entirely too easy.
I have gotten in on several deals that don't last very long simply because there was a new thread and I saw it. I wouldn't have seen it in a stickied thread.
This frenzy is slowly fading. It isn't like you can't start a hunting and fishing or kayaking thread just because we are discussing guns. If you don't like the gun threads, skip past them and go to the "outdoorsy" threads. It's not that hard.
