My reasons are the same as yours, as far as the Tav goes.
BT, I still scan just 'cause it was never really a point of contention for me and to be honest I think they do ok with that part of their program.
The Tav will never work for me anymore. I have no reason to go out of my way to anger or offend people, but I expect conversations between adults to stray from the line now and then. Within some undertermined level of reason.
Same as any other place where I like to go to have fun.
I would rather deal with a real person,(foibles and flaws), and be offended - Than talk to some sterilized version of what that person would actually like to say.
