The no politics rule is as simple as staying away from partisan bickering,
@Deya . We can talk about Medicaid, SNAP, immigration, abortion, gay rights, gun control, etc. etc. etc.... but as soon as someone (sadly it happens all too often) starts bashing a politician, an administration, a political party, and so on, it crosses the line. Some line crossers, I do believe, get a kick out of doing it. And some who used to do it are now banned. It's not about the topic per se, but about how it is handled by what are supposed to be mature adults.
