Facebook gets its content from users. Blame them. This is what the public wants.
Absolutely not. Users didn't sign up for this, they signed up to stay in touch with their friends. Facebook pulled bait and switch. At no point do they actually explain the implications of what their users are doing.
Many of these things only exist in the minds of MRAs and incels, people who feel that the world is against them.
Logical fallacy - poisoning the well. Not a good start.
Trigger warnings: Simply asking someone to warn you if they are going to start talking about something that might cause you severe mental anguish doesn't seem unreasonable.
The problem is that they are not asking, this implies that it is possible to reject this request. They are dictating, and using it to censor and enforce groupthink. I think even you would agree that freedom of expression and free exchange of ideas takes precedence. Last but not least, people demanding these trigger warning presume to speak for PTSD people. Why don't we let them decide it for themselves?
I know a guy who was attacked by a dog as a child and it's left him with a fear of them; I wouldn't just go into graphic detail about a dog attack around him.
Would you also demand all dog parks were closed because of this? Because this is how 'trigger warnings' are used in practice.
Safe spaces: Yes, sometimes people want to discuss things in a semi-private setting.
Not quite. People feel entitled to exclude others in a public space. Equal and unrestricted access to public spaces is sacrosanct, the alternative is some flavor of Jim Crow.
Computer programmers do it byte by byte.
