I would not consider myself "right wing" - I'm an anarcho-capitalist, and have no problem with the vast majority of the social issues embraced by the left. I take issue with the way they intend to address them sometimes but that applies to all parties and to government in general.
Still, I often bite my tongue when guns come up as a topic of conversation in a professional settings, because when I speak on that topic it's automatically assumed that I'm a Republican. Democrats (and assorted other leftists) seem to regularly project their preconceived notions of what a Republican is onto me, and assume that they are correct.
It's almost like politics optimizes to get 50% of the people on each "team" \s.
It's not “politics”, it's the US electoral system, and particular:
(1) single-winner majority or plurality legislative (and state executive) elections and
(2) Indirect federal executive elections where the voters are elected in winner-take-all plurality elections at either state or a mix of state and district levels.
Together, this strongly encouraged a system of two major national factions, each of which strives to acheive a winning coalition with as little compromise on policy priorities as possible, which in effect means minimal size to acheive victory.
Instead we get everyone telling the mob what they want to hear and no one can figure out why the votes counted don't reflect the "consensus".
I watched the video and if I remember right somebody did come up and gave a reminder that they should be considerate that there were Trump voters. They were promptly booed.
