I frequent a few other gun/outdoors forums, and I prefer TFL because of the close moderation.
If you have a valid point to argue, you won't have a problem here. If you simply wish to spew vitriol and hate, you're not going to be here long.
I come here because it's a place for serious discussion, while allowing for a little bit of humor.
The unmoderated/loosely moderated boards are OK if that's what you want, but quickly degenerate into folks trading insulting posts and I just don't care for that.
I've certainly made my share of tongue in cheek posts here, but I don't insult other posters and I'm happy with the way the board is moderated.
Just remember, when you pull the trigger, the bullets come out going very, very fast. So make sure to keep the weapon pointing away from you.
