Anarchists laughing at the thought that tankies don’t want them dead.

Tankies, very often, align with fascists on specific policy decisions. That’s a huge part of what makes them tankies in the first place. Having a different aesthetic does not make them not authoritarian. You can talk about tankies supporting LGBTQ+ when most tankies aren’t actively supporting Russia, a nation notoriously anti-LGBTQ+.

Important part of your second point, other leftists.
