Yes, GLBTQ youth should be allowed to make their preferences known in school, because that is a free speech issue. They need to be prepared, however, that another student might say that they disagree with that lifestyle, or that they think being GLBTQ is a life choice. Free speech goes for everyone.
I believe there are many cases where gay, lesbian, bisexual, trangender, and questioning youth would have a hard time keeping their sexual preferences a secret in school. For this reason, it should be allowed to make it known. When you interact with the same group of people they're bound to get to know you. It's almost impossible to keep such information out of the school setting.
Yes, the LGBT community has the right to be who they are and that includes in school. It's all natural and we have no reason to not give them the same respect that we give someone else in this world. It's time for this country to move forward in the right direction.
Denying youth the right to free express and state their sexual orientations in school would be oppressive and unconstitutional. There are no legitimate reasons for forcing those youth who are gay, lesbian, bisexual, or transgender to remain silent if heterosexual youth are afforded the right to do so. Such discrimination should not be tolerated.
It's not that hard to keep it a secret. Just not talk about it, is that complicated? It's an immoral act in the beginning and our children should not be introduced to it until they are a bit older. How should I feel safe anyways? Have fun with your gays, I'm switching schools.
