everyone on tumblr isn’t liberal, liberal is actually more of a conservative but they’re “left-leaning” because they still hold a lot of conservative views. i think everyone on tumblr would be more considered just “leftists” which are people on the direct opposite & much more radical than liberalism, but conservatives consider anybody who isn’t conservative a liberal
that’s specific to the United States though, liberalism is defined differently depending on a countries political spectrum
i think the US is this way because it’s skewed so far to the right atm that any slight opinion outside of conservatism is considered a liberal opinion, it’s the bare minimum. most leftists don’t actually see liberals as leftists because of this
