Racism and these kinds of stuff

Lately I have been seeing a lot of racist memes on instagram. Like how black doctors might steal your organs, or a post of black doctors celebrating with a comment underneath saying: I'll stick to asian doctors or stolen lab coats. While they are intended to be humorous, I cannot see the humor, nor can I laugh at them. I find them disturbing and very annoying. Now I've been noticing my friends using these jokes and trying to be funny. Not only my friends, but everyone I aquaint with. And I think to myself is this the way to be cool or liked by everyone? I hate this, I cant stand these people, even my friends I mostly try to avoid them because they are like this. And what is going on with people to post these shitty stuff. Even if they are intended for fun, they stem from somewhere and they can lead to people actually believing in this. I can write even more stuff about this because it is really getting on my nerves. What do you think?
