I agree!
This is not a 1 st amendment issue, A&E is not democracy nor is Bass Resource and each can institute their own policies. A & E is attempting to cater to their overall viewership, given what I believe is that viewership I think the decision was the right one, and it is all about ratings. This is really no different than a radio station not wanting to air or terminate a host that may have opposing views to that of the station or the majority of it's listening base, again it's ratings and sponsors.
Any on line forum has the right to edit or delete any post as they see fit, A&E has the identical right. If one does not like the policy of a forum, they go elsewhere and by the same token if unhappy with A & E then watch another network.
Really makes no difference to me what happens, I watched the show once and that was enough for me.
