Well... ya gotta understand that there's people of all ages here from all over the world. If somebody didn't understand your post it could be that their first language isn't English. It could be that it's a 12 year old kid.
It could be that somebody is purposely trying to be a pain just to get a rise out of you.
You probably don't have a lot of experience using forums because you'd know not to take anything said on the internet personally. Discussions go off in all directions and there will always be people you don't get along with.
Think of it like being in a huge auditorium full of people having a loud party.
If you don't like what a few people are saying in your group.. instead of standing there complaining about it, go to the other side of the room and talk to somebody else.
