I have seen what you are talking about Sannah and I'm sorry you've been subjected to it. It is hard to want to come back and be a part of a community where you feel there is someone around that doesn't want you here. Please know this though- there are many, many people here that find your comments valuable and would feel deprived of your knowledge and insight if you stopped posting.
