I'm not normalizing anything. I'm reacting proportionally. Typing some dumb bullshit on the internet for attention (and finding success, I might add) is not the same as doing it IRL. It's cringe, it's obnoxious, but it's not really "dangerous" per se.

If you remember the internet 10 years ago you'll remember that saying weird shit to women online was completely normalized to the point where it didn't even register as an issue for most people. We've come so far in correcting that by 1) making the internet more inclusive by way of accessibility, and 2) having the type of discussion that can actually change people's minds and provide new perspectives, i.e. realistic discussion where we react proportionally.

There's no way to tell if it's supposed to be funny or something, in written communication, so there's no choice but to take it literally.

The absurdity of it points to a joke, IMO. Dirty, off-putting and likely contrary to the conversation going on in the rest of the post it was left on, which may even be further hinting at a type of humor intended by the user (IE trolling).

It's called giving the benefit of the doubt, do it for your own sanity. Is it gross and distasteful? Yes. Is the poster a mentally ill and a threat to themself or others? Probably not.
