Just want to point out that this is a misuse of the word schizophrenic; if you are going to link extreme swings to a psychological disorder, the one you're likely looking for is bipolar. Simplifying it, schizophrenia is when you see and hear things that aren't there.

Foucault would politely disagree; he used "schizophrenic" (literally, "a mind split into pieces") to describe the way that (post)modern society uses symbols and signs to point at cultural features, without actually understanding how those cultural features interact. In such a society, the signs themselves, and they way in which they chain into each other, become the primary meanings, replacing the cultural features entirely.

The parent reasonably points out two families of sign-chains and sketches how they conflict by emphasizing how the signs espouse conflicting opinions on male sexuality.

Foucault would probably disagree for more reasons than that; specificity and certitude in regards to psychiatric illnesses or how they are described wasn't exactly something he jived with

There's a wide gap between hooking up with someone who you were messaging on Tinder and touching people at work...

Porn and other media content are even more obviuously not real...

The key word here is "consent".

Sex is fine. Hell, sex is great! Just don't do it with someone who doesn't want to do it with you.

It's actually pretty easy: do you have consent from the other person for your actions affecting them? That's really all there is to it.

Not really. There have been cases of people regretting what they did and retroactively revoking consent, leading to trouble for the other person. It isn't as easy as you make it out to be.
