I read this a couple weeks ago when it was originally posted. Its always interesting to see why a liberal would "convert" so to speak.
to me, in the here and now, the modern liberal has some real contradictions to overcome that aren't being well thought out or discussed, because IMO they cause to much mental incongruence
for example:
the desire to help the poor and downtrodden Americans vs the desire to have wide open southern border which undercuts wages & jobs for those same poor.
the sensitivity to all things considered sexist or paternalistic in this country vs the ignoring of heinous crimes against women in Islamic world.
the classic ideal of "liberal" values of free speech, expression, truth to power vs the modern liberal desire to squelch free speech on the internet, in the news, on campus. This is especially obvious in the news today, where major old school networks refuse to report certain stories that are deemed harmful to Democrats, and where DOJ and the White House has colluded with media to frame stories.
