Lots of kids get bullied for a variety of reasons. Since homosexuality is faddish these days, I doubt that kids who might be entertaining the possibility of being homosexual are any more or less likely to be targets of bullies. And kids who are bullied for any reason are at increased risk for suicide.
So, instead of opening a school for kids who are too young to "know" that they are homosexual, how about laws against ALL bullying?
The message here is not that bullying is wrong, or that whoever came up with this idea cares about saving lives. The real message is that no one in the system cares a wit if a kid is bullied, unless that kid claims to have one specific kind of mental illness.
How about realize that for a lot of the bullies, you have parents who just don’t care about what their kid is doing, and a suspension is a vacation to them? If a kid spends his suspension time out of school as a punk and stupidly attacks a community watch official who fights back and kills him, what makes you think plenty of other kids could be bullies and not care because suspensions don’t mean much more than a day off school to them?
