I'm sorry I see nothing "disrespectful" or "offensive" about Bamafan's post either. I even had my husband read it and he couldn't see what could have made you so angry either.
The only thing I could POSSIBLY see is that she used the term "mutt". I don't think she was being rude about it though. I call my babies "mutts" all the time. Sometimes I call them that lovingly, sometimes I call them that jokingly, and I've been known to call them that when I was ticked at them.
Sorry, I'm not trying to upset you (or anyone else) even more, I just honestly don't see what was so wrong with what she said.
