I don’t think they really are “light years ahead of the right”. Most of the difference as far as I can tell is in how they talk-- not what they do. Liberals fundamentally just believe in the status quo. MLK Jr saw it the same way when he described " the white moderate" as the greatest obstacle to change.

I’m definitely willing to engage liberals (and even conservatives) in honest conversation when I feel the context warrants the effort. Lemmy rarely seems to qualify.
