Where did you get the impression that Lemm.ee is (more) right-leaning?
Lemm.ee does not really have a leaning (in the fediverse).
Lemm.ee has awesome uptime, hands of moderation, up to date Lemmy, and doesn’t defedarate (we live in the glorious age of Lemmy 19 and not in the dark ages anymore; the user can block stuff).
Both c/conservative on Lemm.ee and Lemmy.world are currently unmoderated (no community moderators).
The one community moderator on .ee got banned for some Nazi shit.
Now in both communities there is lots of love for trans people🏳️⚧️
