Oh please don't stop posting. I know some can be rude and obnoxious, but we love you!! Don't leave!! You can always report a post if it's unacceptable. The admin will review it and I believe they will suspend for too many nasty posts.  
I'm so sorry you're getting attacked. I know you are just trying to help people and it sucks when people shoot you down. Don't be discouraged, keep your head up and ignore those people. Whoever started the stilled enjoyed your help even though some broke in and weren't nice.
Hugs to you!!
