No, but kids can be very cruel.
I'm undecided about this issue. On the one hand, this seems to go against the approach of "one group of people is as much a part of society as another group, and as such the idea of full integration and co-existance between everyone should be promoted". But on the other hand, children latch onto traits in anyone that are different, and with the little gangs and cliques that are formed between students... a gay student's life could be made extremely difficult, and prevent them from enjoying the full academic experience.
Educating students on LGBT issues, promoting acceptance, and strictly enforcing policies against discrimination are all positive steps... but I wonder whether they will have the desired effect. Often children don't bully others because they actively hate, or don't understand those they bully, but because they want to be accepted themselves within their little circle of friends, or to give themselves the illusion of control over someone else, or they do it to take out frustrations going on within their own life. The other person often has very little to do with the motivation. Educating people with that mentality can be like water off a duck's back. And the prevalent mentality could still be "They are not like us... Hulk smash!!"
I don't know, ideally it would not be neccessary to segregate students, and ideally attitudes could be changed with enough effort and application... but things are rarely ideal.
