How and why is reddit so liberal?

Amidst all of this X banning here and talk about discontinuing subscriptions and accounts with companies like Amazon and Facebook, it got me wondering why Reddit is so liberal? Don’t get me wrong, I am with the majority here on most of the stances.

It just made me wonder why most users I see on this app are liberal. Is it observers bias where the algorithm gives me that content, or is there an actual reason I’m missing?
