Concern trolling is acting like you’re concerned about the consequences of something.
Like,
If we let people wear masks during COVID, we’ll see more bank robberies because masks are normalized!
Sea Lioning would be if I just kept asking you questions about why masks help, often while asking you to link sources. I don’t actually want to see any sources tho. I’m just going to keep asking new questions and for more sources until you get tired and stop replying.
Because the more time you waste on me, they less you help people who are genuinely asking for it. Plus when you stop replying, I can claim that as a victory because that must mean there aren’t any sources that agree with you.
