I think its been answered. "AS LONG AS WE ABIDE BY THE TOS". Thats an agreement that we enter into with A2K. A2K, as a non-public organization has set up its rules and if we read the TOS, most of the speech they consider as unwarranted, they can dump.
Which apparently they did.
Also, There is no "Free Speech" There is speech which is protected and there is speech whch is not protected.
The First Amendment Center website of Vanderbilt U has a nice listing of the 9 areas of NON protected speech. Maybe A2K, has adopted these categories in its own TOS .
The Atheism Thread, you must agree , was getting to be a running smirchery among a few members.
They were stupid exchanges to start with and they went on long enough.
It would be nice to have it in archives available to us, so that we could conduct scholarly reseaarch into identifying just WHEN the smirching began and who was to blame
