I think you might be misreading.
Don't take this the wrong way... I do not mean this negatively. But I have seen a lot of your posts, as a lot of your threads bubble up to the top for some reason.
Maybe one or two people will say something truly rude to you, then it seems like everyone after that gets attacked by you and shut out no matter what is being said. I don't think you are doing this intentionally, but I do think maybe you should take a step back from the screen and wait before responding at all when you get upset. The internet isn't a good place for emotion, for obvious reasons.
