I realized every time I travel they do a swab test on me. Does this happen to you as well?

I realized that every time I've traveled solo, they always perform a swab test of me and they also carefully go through my bags and even swab test that as well. This can start to delay things but I realized that they don't do it for other passengers. I don't have an issue with it. I tell them I am willing to do and even willing to do a rectal exam. I asked my friends and they said it's probably because of racism and the way I look. They said I look like a predator or some sort of drug dealer.

I was wondering does it happen every time you guys travel solo?
