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.

/r/europe will ban you for insinuating that rich people are making the world worse for everyone because “it’s communism”
