Sure: what you say makes sense, don't get me wrong, it's just highly morally conceited for employees to think they have any standing to have made certain jokes

Sure: what you say makes sense, don't get me wrong, it's just highly morally conceited for employees to think they have any standing to have made certain jokes at a time when it was tolerated, and now they they have changed their own attitudes about what should or shouldn't be off limits in the workplace, that everyone else should find these jokes beyond the pale as well, and be talked down to about what is or is not offensive. A blanket "no politics" rule is fair because it doesn't privilege any particular person's sensibilities about what is or is not acceptable at work. Obviously there is a gray area, but employees who demand these issues be dealt at work and then don't want to face censure for their participation in it in the past are just hypocrites.
