The truth is you are your own opressor, just because anyone exist doesn't mean others have to acknowledge them let alone validate them. It's reality, deal with it or not but it's not ever going to change, not because of the people not willing to have an open mind about the subject matter but the person holding their jaded beliefs that they are unique and should be given respect for their uniqueness. But when you expect to indoctrinate kids about the subject matter that's kind of sneaky and intrusive. Leave the sexuality away from children.
