The silent ideological and political battle of flagging uncomfortable truths is trampling curiosity. Interesting how they get a way with violating the guidelines, and yet people who want to have a conversation are accused of and sanctioned for it.

The small mistake you make is assuming the users doing the flagging merely want to ignore it. They don't want anyone participating in it. The very topic is persona non grata. The guideline itself is written in newspeak.
