On Sunday, a Facebook friend got suspended from posting for 24 hours after he posted a satirical mockup of what he obviously saw as Trump administration discrimination and racism. (That is, making fun of the appointments of "President Poopiepants", the Child who runs the free world.)
Facebook wrote back: “It looks like something you posted doesn’t follow our Community Standards. We remove posts that attack people based on their race, ethnicity, national origin, religious affiliation, sexual orientation and gender identity.”
There's another affiliated concern: the mere mention of something, reminding others of it gratuitously, suggests that the underlying problem is not settled and that it needs to remain in the air, so that some people will perceive a justification to continue the discriminatory behavior just because other speakers dare them to.
