The axiom of political correctness is basically 'If something offends someone somewhere, then no one anywhere should see it.' It's bullshit through and through, I don't think there's anything 'wise' or 'caring' or 'necessary' about this decision.

Actually, no. The whole point of political correctness is that if you complain about it, you prove yourself a douche. The only people who ever being up being PC are those who feel like their rights to be offensive are being questioned, and as such, it's an excellent assholometer.
