My dude, liberals are moderates. The only way you can think otherwise is if you're so far to the right that you've lost perspective. Biden is a typical center-right moderate liberal which is exactly what most Democrats are.
U.S. Democrats are in fact radical about these issues, insofar as they see them as matters of fundamental morality that are outside the political process altogether. In virtually all of Europe, for example, it is well accepted that abortion is a type of social regulation that can be put to a vote just like any other type of social regulation. But U.S. Democrats denounce putting abortion to a vote as a “far right” position.
A good 50% of the online crowd, on both sides (left/right) are *absolutely delusional* when it comes to political perception.
On the right you'll hear Biden is too far left because of the massive public spending, the aggressive NLRB policies favoring labor, the support to unions, anti free trade policy, neo-brandeis antitrust, trans rights speeches and wealth tax support.
On the left you'll hear Biden is actually a neoliberal or center right, because of his stance on Israel, his belief that welfare capitalism is better than socialism, his belief in economic growth and innovation, his past ties with the banking sector, his 1994 crime bill and support for the police, pragmatic climate policy, etc.
When debating online half the time you're just trying to filter out completely delusional beliefs, and it's tiring.
