That's why I like to talk about PDPs history of continued mistakes. You'd think someone who triggered the adpocalypse by doing stupid nazi shit would stop for a minute and think about suggesting a channel like that, and a video that shows the death of Heather Heyer. 
So assuming it was a mistake, what 
should he have done to make amends for that mistake?
Put out an apology video, explain how and why he made that mistake, and edit the original video containing the mistake to remove any implied endorsement of 
someone elses channel?
Because thats literally what he did. 
I mean, you might not know that, because the mods were quick to edit that topics title into what it is 
now, but not so quick to update with a follow up.
But you and I both know that doing that 
is not enough for era consensus, that this will be brought up in 
every future topic about him ad infinitum, and realistically, there is 
nothing he can ever do that will ever not have him denounced on general principle immediately.
