That’s because there’s not one single definition, especially on Lemmy.
To most people in the US, it’s anyone politically left of center. Primarily Democrats.
To leftists, a liberal is anyone who espouses capitalism. Republicans are liberals because they fucking love capitalism. Democrats are liberals because they believe that, despite its faults, capitalism is the best system and that it can be improved with reform and regulation. Since Lemmy abounds in leftists, you will see this usage a lot.
Finally, to conservatives, liberal is a slur. It’s the OG woke. It means anyone we don’t like. Conservative politicians even call each other liberals, especially during primary season.
