That said, I usually do not support dragging screen caps of one to the other but that's because it encourages unnecessary tribalism of "oh look what they said about "us" lol " or "look how dumb they are/I am silly" but at it's core we should never diminish free social sites because a few stupid people are in it least we forget that we are all stupid in one thing or another.
This is coming from a 35 year old happily married man however that has enjoy what life has given him so I likely lack the narrative need to be upset at other places politics.
