That’s reaching a quite a bit. Reddit itself is very left leaning. Pair that with the fact that the (probably few) ring wing people leaving Twitter recently might not be interested in a forum style platform such as Lemmy.

My guess is that the number of right leaning people joined Lemmy in this last wave of new accounts was small in comparison to the left leaning ones.

Reddit used to be very left-leaning, but I don't think that's true anymore. Even if you look at a community with a conventionally "leftist" moderation like /r/europe you will see a huge amount of authoritarian and outright fascist comments.

You’re aware that leftists can also be authoritarian, right?

The definition of right wing politics is being pro-hierarchy. Or believing hierarchy and inequality to be normal. This fits well with authoritarianism.

The left, by definition, wants to end inequality, or make things as equatible as possible. This is the antithesis to authoritarianism.

So, no. I’m not aware of this and don’t believe it. If someone told me they’re both left and authoritarian I would tell them sticking feathers up your ass does not make you a chicken.

The libertarian left is anti-authoritarian. But unless you are going to exclude all marxist-leninist from the left, regardless of their advocacy for equality and opposition to the capitalist system, left authoritarianism obviously exists. I think perhaps you are engaged in a no true Scotsman fallacy?
