Still not sure about content warnings. Not so much the general application, which I don't mind, but over-zealous enforcement.
My partner's on a profession-based forum on fb where many members know each other irl. A member was criticised for not using trigger warnings for a sensitively worded death notice about a fellow forum member. The thread derailed into upsetting meta discussion.
I can see it might be polite to use them, but sad if they become a tool to bash people with.
