Steven Crowder is the guy in that meme. He has a YouTube and Rumble show called Louder with Crowder. He also does stand up comedy. He is conservative and pro-gun. He was born in the US but grew up in Canada. Every once in a while he'll get permission from a local college (he lives in Texas now) to set up a table with a sign that says something controversial to liberals and asks them to change his mind.
He films those segments as part of his Louder with Crowder show. He is always very respectful to the students who try to change his mind. He never argues or demeans them. However he does his homework ahead of time and shows them facts and statistics that back up his statement.
Liberal college students, being some of the worst people on the planet, will try to interrupt his show with all sorts of idiotic nonsense. Most of the time he doesn't air those parts of the show. He mostly just shows the respectful conversations he has.
Someone, several years ago, decided to use an image from one of his shows as a meme and now there's tons of memes with him or other people superimposed over him being used as memes.
That's who Steven Crowder is. I've tried watching his show and I don't really care for it, not because I disagree with him but because I don't think he is all that funny. Just my opinion, you might think he is funny. I do like his Change my mind episodes.
