1) At my school, Christian kids are far from being the ones that are picked on, cast aside, etc.
2) I agree.....but why did you use "secular" as a criticism of BVSD and schools in general?
3) We do teach skills needed to survive in a complicated world....and I agree that schools SHOULDN'T be in the business of the other stuff.  However, too many parents in today's society don't hold up their end of the bargain.  A kid won't learn well if they're starving, or sick, or psychologically damaged from their parents BS.  Too many parents don't teach their kids how to function and act properly.  If the parent doesn't do it, and the school doesn't do it, who will?
4) Sure, I could tell LGBT kids that.....but I'd be lying.  I have told them that things get better, but I'd never tell them that no one in the real world cares, because that is BS, and it would be a huge disservice to do so.  If you don't care, then kudos to you....but to say that no one does is a false reality.
