Gays have been accepted for a few decades now.

By many, but not as many as the media portrays.

Divorce was also accepted by more, and much earlier, but that never made its way into a Peanuts comic. Peppermint Patty's mother died when she was very young.

That line was put in because it is NOT universally accepted. Otherwise they would have left the source material alone as there'd be no reason to bother it.
