Picking on gays got old and ineffective for Republicans. So, their newest minority to spread, fear and hate over is to pick on transgenders. I sure don't see Republicans helping trans kids with their problems and only want to make things worse. In most cases, wanting to ID as the opposite sex is the kid's idea, not that of the puzzled parent or teacher.
I've heard on podcast of a councilor advising parents to send their little boy who has been IDing as a girl since age 3 to send him to school dressed as a girl to start first grade, so there's that for Republicans to be worried about in their hate and lack of empathy. I'm simply thankful to God I'm not the parent with such a child and don't want to stir up fear and controversy over it. Why can't Republicans feel the same way?
There are surely Republican teachers in Colorado, especially in the High Plains part, so they surely feel insulted.
