He's not censoring. If he had been censoring some posts would "magically" disappear. He's just giving his opinion.
Just because his opinion is different than yours it doesn't mean he's censoring.

"Oh look, you brought the "bearing and raising children" BS into it after I asked everyone not to. "
That is not an opinion, it is an order (and using foul language) that people not mention children.
Children are relevant to marriage in my opinion.
