It is new for me to feel that way but I reached this point last month with Tx and set some new boundaries for me with him and now I'm setting more new boundaries for me. I know this isn't a topic I can post and ask for advice about although sometimes I wish I could do so. It is a situation that I have to figure out on my own and just do my best.
I am sorry that you aren't comfortable posting about Tex - but understand.
Sometimes a person is offering their opinions, he/she gets very attached to their own point of view. And sometimes when that happens, he/she starts to take it personally if you do not follow his/her advice. And sometimes that leads to disparaging the poster personally and/or ridiculing the posters position. And sometimes the person catches themselves - sometimes they don't.
I am not above this myself. Just check out the flirting thread if you want to see me in reactive mode! LOL! I personalized the issue based on my own personal experiences - instead of posting on that thread in accordance with the intent of the thread originator.
You could consider setting some ground rules for responding to posts about Tex on the BB. NHill posted a line on his thread to the effect that when a person posts a do not tread on the grass sign on a lawn and the posters of the sign happens to be the owner of that lawn, he honors the sign. A lot of people agreed with him. So I suspect a lot of people will honor any ground rules that you request that people honor.
And if people don't honor those ground rules - you can ignore those posts or simple set a boundary addressed to that poster.
I know it is an awful lot of work... But while we have our differences people do seem to listen when someone makes a genuine request of the other posters on this BB. And it may turn out to be a valuable experience that will help you out in the real world. I think DR has an entire chapter on asking for what you want.
