I have no idea what they are doing since I don't live in Seattle and you didn't post any links to any legitimate news sites. But I'm quite confident that no school is referring sex change surgery for 11 year olds as you just asserted. Most of this articles I see along these lines turn out to be unsubstantiated fearmongering of little actual substance.
I also don't think it is any of our business how any particular child and his/her parents struggle with and deal with anything to do with sexuality and gender. Not my business, not your business, and nobody's business but theirs.
I also think that it is little more than bigotry, hypocrisy, and hatemongering for the right to obsess about this particular issue compared to all the ACTUAL threats to health, life, and safety that our children face every day in this country. We used to believe in things like freedom and privacy in this country. I guess those days are over now.
