They never knew. Michelangelo was not openly gay. If he were, he would have been thrown in prison or executed.

About 3% to 8% depending on the study.
It means your parents are stupid. Like: "Can you come to the party?" "Nah, my parents won't let me." "Well, your parents are gay."
As of 2014, in the US about 20% of gay couples are parents.
