You are so correct and it’s apparent that cultural Marxism is popular thought among those who consider themselves Republicans. Despite popularity it is still destructive and I don’t see how any society can survive it.
And for the unthinking scoffers: No, girls playing on boys' athletic teams all by itself won't destroy society. The underlying utilitarian, utopian socialist ideology which leads folks to think (among other things) that girls playing on boys' athletic teams is just peachy will destroy American society. That is the purpose of utilitarian, utopian socialist ideology.
