Trans Students matter- legislation that protects them and supports them in an public/academic setting will overall help them as well as the rest of the student body. Anyone who disagrees in all honesty wishes to be just able to perpetuate a mindset that allows discrimination against those who are different from that one person's perception of what should be the acceptable norm.
If we are to embody a nation who is said to be a melting pot, we have to accept this as truth, that the rights and needs of all persons, no matter how similar or diverse we may all be, even as minors- are to be acknowledged and protected. And that means accepting and protecting the rights of trans minors in our schools.
