You're right that Biden isn't much of a Leftist, because he wasn't doing much of anything at all during his Presidency due to his declining mental state. But that's why I said the Biden administration and not Biden himself.
The point is that I can't say these are "liberals" since what I'm claiming they have been doing is obviously very anti-liberal. Genuine liberals I wouldn't have as much of a problem with. I use the term "Leftist" to refer to their stance on social issues due to the lack of a better commonly accepted term, while obviously they are definitely not committed to hard Left positions on economic issues as you seem to intend to point out.
I myself might be further to the left on economic issues than many Democrats since I have come to the realization over the past decade that woke capitalism is capitalism. All that ESG and DEI crap is the free market at work and therefore, I've come to realize that I don't like the free market after all. Some of the left-leaning types I remember arguing with twenty years ago turned out to have had some valid insights on economics where I was wrong. Now if they could just recognize the fact that men can't get pregnant, they'd be well on their way to a sane governing policy.
