I find that the median person who disagrees with me, actually agrees with me, but I accidentally triggered their social media PTSD and they flagged me as an enemy because I didnt slavishly polish their preferred set of boots.

That too is a major problem, in theory you could be posing fine questions but they are already politically or socially tainted so it's game over before it even started, you will get zero actual new thought from the person you asked.
