While true, at least in my understanding of the world there is a massive difference in people involved in CSAM and people watching porn. The latter one is probably like 80% of humans with access to internet, the first one is hopefully a tiny bit smaller. Also, people are probably very aware that the latter is widely allowed and done by mostly everyone, and the first one is highly illegal, highly enforced and morally completely wrong.

I would not mind browsing porn on my work PC. I wouldn't do it, but I would not have a very bad feeling while or after it, because so be it. I don't think my employer can fire me for that.

I would mind about doing CSAM activities though.
