Do you think that the photo was needed to understand the context? I think so. There is a depiction of Lincoln as he's about to be assassinated front and center on
Wikipedia's article for the assassination of Abraham Lincoln. Granted that this artwork became part of the Public Domain, so the only rational explanation to why Wikipedia's grand and wise editors refuse to allow that photo of trump with his fist pumped on the article would be because of copyright issues. Though their editors are caught with their pants down and bais showing because they can't use that explanation because of how
they distribute the photograph elsewhere on the website.
So.. orange man bad! Basically, their chief editors don't like him. They don't like this picture of him where he looks triumphant from surviving an attempt to end his life, so they wont give it its rightful association with the
new Wikipedia article on the attempted assassination of Donald Trump.
I don't even like Trump. I think he's a megalomaniac and fool, but come on. The particular insanity or cognitive dissonance of some of Wikipedia's editors shows that in any position of authority and anywhere that humans are there will always be irrational decisions.
