all they had to say is "no we aren't tankies" and people just took them at their word lol
IMO it's a little more cynical than that, they rephrased the narrative into one that they could cleanly reject and be quoted on. As others have pointed out, it is almost a certainty that 1) they do not consider themselves or their ideology to be fascist, and 2) they aren't supporting genocide if they do not acknowledge that the peoples in question are actually subject to genocide.
Edit: ...Which you've already affirmed in one of your previous comments, my bad.
Yeah, pretty much. To not reopen you have to have absolute confidence that no one on the mod team will succumb to the temptation to steal ownership of the sub. The fact that some subs have fallen prey to this (like /r/piracy) is why mods have been wringing their hands and reopening subs left and right.
Honestly this shit is early IRC drama all over again; kick all the other ops from the channel and it belongs to you, provided those people aren't registered in the ChanServ. /u/spez is the ChanServ, and he's letting everyone know he's willing to look the other way.
