Parents who want to shelter their kids from the real world and avoid explaining trans folks should probably just homeschool their kids if they are that concerned or pay for a private school that believes what they believe. Public schools should support all people and teach about all races, genders, orientations, etc. I don't have kids but I want the kids in my state to be up to date on this stuff if they are going to live here and work here some day. Makes for a better and safer society if we aren't all beholden to archaic beliefs from out dated religious types.
