Yeah, people have been slinging mud here for years. I believe the term "Congresscritters" was used for the very first time right here at FR. (not that any of them would show up here to 'hear' it) As you say, you get used to it. I've been called a pothead on the WOsD threads so many times it's not even funny. You use the elephant metaphor and I use the duck's back metaphor.
Nor should you get upset if somebody calls you a troll. Hell, I've been called an ogre and I consider it to be an apt description and a compliment.
Enjoy your stay here however long or short it may be. Your posting history will speak for itself so after about a decade or more you should be fine.
Sometimes it's a bit difficult to be patient with people who have absolutely zero patience for me. None. What-so-ever.
I would suggest, however, that you do need to work on not making qualifying statements like that. It gives the impression of being disingenuous.
Well, I'm not going to change my mind on the basis of new and INvalid information!
Would you? :-)
