You're not obligated to give away your mind for free. You're free to share, of course. But sharing implies reciprocity, a back and forth. The internet used to be like that, but if the environment changes, you adapt your behavior accordingly.

In the long run I think it's time to starve the system from input until it's attitude reverts to reciprocal. It's not what I'd want, but it seems necessary. People learn from consequences, not from words alone
