The fact that there are "verboten" images says plenty.
In fairness, we certainly do not need outright porn or four-letter vulgarity to be posted in images or in the discourse, BUT - the Trump snowflakes have stated their offense at having any comparisons made between their devotion to a cult of personality and the devotion to other historical cults of personality such as Hitler, Mussolini, Hirohito, Idi Amin, Robespierre, Lenin, Stalin, Kruschev, Johnny Depp and Madonna.
Because those comparisons hurt and get too close to identifying the zeitgeist that animates them.
One of the ever Trumps has a picture of Nazis executing people in her signature.
Perfectly acceptable. The image is not making any references to Trump or his supporters. It's referencing guns control, an issue that has not yet been touched by Trump Tweets.
