I didn't comment on them because one, there's a lot there, and two, they said they didn't want to have a debate.
I guess in hindsight they weren't even necessarily stating their positions on these things (although I think the way some of it is talked about is revealing).
Honestly I don't even know that I disagree that the left has moved left, but I don't think I'd express it without some major caveats, because politics feels very convoluted right now.
Generally, I think id agree that the democratic parties positions haven't shifted much and that there's a greater visibility of things I'd consider far left, but I don't know to what degree these are just shifts in visibility and how closely tied the party is to the base, vs which are actually tied to underlying changes in views.
