I read though the suggestions. So "trigger warning" is now problematic and the proper alternative is "content note". And "Preferred pronouns" is hate speech, because you imply that pronouns are merely a preference, as if the person can choose their identity. Godspeed.
As the website doesn't work for me, I genuinely cannot tell if your examples are sarcasm or come from the website.
> Instead of: trigger warning
> Consider using: content note
> Context: The phrase can cause stress about what's to follow. Additionally, one can never know what may or may not trigger a particular person.
So the examples are not sarcasm, they are literal.
