Modern American Nazis have figured out they're supposed to smile and talk friendly and wear a nice suit and pretend to be normal people with normal values even as they talk about committing atrocities on a daily basis.
The useless format of these debates allows them to get away with it, as most viewers are woefully uninformed by the media of what these people stand for and the so-called moderators aren't going to tell them about it either.
That would be biased!
