Treat each other with the same respect you would if you were talking to each other face to face. If there's a good chance the person you're talking to would punch you in the face for saying what you're about to type, it may be a sign that you want to reword your post. Unfortunately the relative anonymity of the Internet allows people the world over to say things they would never say in real life without fear of any repercussions.
Try to keep debates friendly. While it's fairly well understood that 10 gun owners will give you 20 opinions on the same subject, the key to disagreement is to keep it friendly and sometimes realizing that the best option is to agree to disagree. Don't let a debate turn into a personal fight, that is childish.
Also keep in mind that your words reflect on the Pennsylvania Firearm Owners Association and all firearm owners in general. Fair or not, if you come on here and act like a jerk people are going to associate your bad attitude with the organization and firearm owners as a whole. Please don't make the rest of us look like uneducated, small-minded idiots just because you choose to be.
