If you're going to browse a website that's known for being full of awful tech-bros, racists, and fans of paul graham, it's usually best to avoid advertising that to the rest of the internet.
Most sites are too lazy to do anything based on referrer, but there are several sites out there that go the extra mile to put out a welcome mat to people coming from this wretched site.
No, I think you've confused "I don't like these people and if you don't like them either here is an easy way to avoid them" with "they're stomping on my rightgs!!!!1!!!!!1!!! waah!"
Advising someone "you should clear your browser history after going on 4chan, pornhub, or hacker news" isn't exactly "thought policing", nor did it mean to sound like I was yelling.
It's just a little informational thing. Like, evidently parts of the rest of the internet have realized how bad 4chan and hacker news are, as we can see by the referrer-detection stuff. I'm not telling you to stop visiting such bad websites, just telling you that you may want to cover your tracks if you intend to fit into polite (internet) society.
