For most people it is not anywhere near the level of psychosis. However, for a few it seems that they imagine much more than is posted, then react to what they have imagined. (here we are heavy into the grey area)
Kind of related: the internet is filling up with little videos of Trump backers losing their shit in public. Which was predicted, and perfectly in character, and most alert Americans had sort of mentally bunkered up at the prospect, but I'm not sure it's what the OP had in mind.

Soccer normalized this kind of thing in its native habitats long ago, maybe we're just catching up now in the US.
