Lemmy has this weird point of view, if you aren’t extreme left then you are not left at all. I’ve seen people make comments like "just be honest you aren’t a liberal ".
Generally, the non-Marxists and non-Anarchists on Lemmy are absolutely liberals.
They want to move the bar so they don’t have to claim they are extremist. I wouldn’t worry about it.
I don’t think Leftists here care about being labeled an extremist or not, the point is to pursuade more people to become Marxists or Anarchists by actually talking about their views openly.
