You have also, in the past, discouraged rhetoric and accusations (a/k/a flame wars) that thrive on other parts of the internet.
It seems that THAT means of operating FR has gone by the boards, at least for now.
I have no dispute that you can run your site however you see fit, and I'd like to stay.
But as for the Presidential stuff - I can't clearly see the line that one can't cross, and it's probably better for me to stay away from those threads.
I haven't seen you engaging in what was most problematic among many of those banned - they would get after issues in Fred or other conservatives that they had no problem accepting in their candidate.
"Fred is pro-choice!" they would gleefully proclaim because of some ambiguous statement Fred made in 1994. Never mind that he has the worst ratings possible from NARAL and Planned Parenthood (which is a good thing to us), whereas Rudy is a champion of choice from NARAL.
"Rudy has the same views on a PBA ban as Duncan Hunter!" This one was particularly loathesome - just because Rudy now says he supports a PBA ban, we are to forget he supported Clinton's veto of such a ban, and otherwise fought ANY legal restrictions on abortion - and also considers public funding of abortion to be a right.
Those are just two examples of many. If they had just stuck to their endless repetition of discredited Rudy talking points, they probably would still be here. But when Rudy started losing grounds, they made the mistake of using the premier conservative website as a platform to attack conservatives. And that finally did them in, as it should have. It wasn't like they were not warned, repeatedly.
