In general, aligning with Tankies for any reason, ever, will just trigger a reactionary bias against whatever message you're promoting. I'm not saying I dissagree automatically, but it's the opposite of helping your case.
When Tankies agree with a statement I have to stop for a moment and reassess how that statement can be used to maim and destroy western democracies or if they're just making another show of pretending to have morals.
