For the ~3 people it's relevant to, I've got a second account.
It's on liberalism.masto.host, an instance for people who support and are interested in liberal politics. It's UK Lib Dems so far.
There, "liberal" doesn't mean what USians mean by it (especially when we use it to mean "disparaged centrist" though that's increasing in the UK too).
Masto is all anarchists and commies so I'm having to come out but honestly liberal doesn't mean centrist. :)
