Other Trump memes also exist, such as one with him shaking hands with Hitler or dressed like Stalin. Why doesn't he just forward some of them as well, as it's all a joke? He doesn't do so, of course, because, rightly, they're offensive and he doesn't want to be seen as endorsing their message, which is what a White House forwarding does. And, again, all that is aside, as amplifying this meme only has a downside. No upside. He gains nothing from it. Instead, he alienates yet more people who probably voted or back him. It was an act of political stupidity.
