So did Jesus. But Jesus didn't make mockery of His Mother. South Park does.
I'd argue, in fact I have argued in my numerous posts to you on this issue, that the ones making a mockery of Mary are those who worship bizarre apparitions of her, in everything from tortilla chips to moldy window panes to bloody tears reportedly found coming from statues.
Agree or disagree on that.
FWIW, I don't blame the bishops and the church for being upset about this! I wouldn't expect any less! That's how they are supposed to react. But at the same time, the point raised might still have merit to many.
