No denying this guy should of covered himself better though to be fair so many people make memes lampooning everyone under the sun. It's been a thing since people realised broadband connections allowed you to post a bunch of the things without the connection dying like it did in the 56K era.
So it's a bit rich CNN suddenly deciding that a meme image for basis of comedy is encouraging violence. Hell one of the first major animated memes was that one of Zinidane Zidane headbutting another at 2006 Soccer World Cup final
(just to prove the vintage, this video cites the YTMND page dedicated to this event, good times)
I mean let's put this in context, even in the original video Trump and Vince were play punching each other. Zidane wasn't - he legit lost it and attacked another player in the final minutes of a major final. Yet people still would mess with it and chuckle about it, it never took away from the fact that what Zidane did was utterly stupid, poor sportsmanship and shouldn't seriously be copied. The press as I recall also had no problem having a chuckle at some of these too.
That and part of what makes western society better than the rest is the freedom to lampoon and be critical of higher powers. It's saddening that so many liberals believe that an attack on free expression is a good idea when some of the celebs have visited countries and seen & heard first hand what happens for fancy TV Travel Docs.
