By “cp” you mean loli hentai, fiction about child characters, I assume?

Plenty of people do follow loli hentai blogs and servers, because it’s perfectly legal to do so in the USA.

A person who regularly frequents 4chan, or who downloads pervy anime series might genuinely feel unsafe transporting their computer across the border to where those things are illegal.

It’s not fearmongering to spread awareness when the legality of something common differs across two sides of a frequently crossed border.
