If PC means foolish, then yes, these people are indeed very PC.
...and they are causing untold damage on the lives of their children.
The comments at the article are excellent, by the way:
“I find it real strange that the parents are gender neutral but both sons are wanting to dress like girls. I think the parents are in fact encouraging wrong gender identies. (sic) Instead of encouraging these BOYS to be comfortable being boys, they are actually pushing them to be more girlish. So if they say they are gender neutral then why are both boys dressing like girls? Do they have a problem if their BOYS wanted to wear nothing but boy clothes? I bet they do because they are pushing their own hang ups on these innocent children.”
Never forget, the origin of political correctness was called “cultural Marxism”.
