It's an edit. In the original, the TV screen makes it look like the guy on the left is threatening the guy on the right (the foot looks like a knife). It's meant to be a commentary on how biased media coverage can essentially reverse the roles of the oppressed and the oppressors. And this edit was made to show how in America, republican media coverage tells people that the democrats are "sucking off" leftists, even though democrats don't agree on a lot of things with actual leftists in reality. The caption explaining all of that has been cropped of, you're just meant to know it, which is what makes this meme funny.
You'd think that they are just trying to stab each other, like normal kids would. But actually they are doing something even worse. Look at this picture, they are homosexuals! They are giving each other love! How degenerate.
It actually existed for a short while, before its home instance shut down. I even posted their (under a different username). But there were like 5 posts total lol !memritvmemes
