I brought it up to make a point that no matter what you feel like inside, you still look like something on the outside, and it is that something on the outside that you are initially sorted by. If the teacher asks boys and girls to line up, it's not forcing them to conform...it's just logistics. But as I said, the school should fully respect a child that feels more comfortable with the opposite sex or in a neutral third line.I don't see the point of bringing sexuality into a conversation about gender.
Is there a third sex? Remember I'm talking physically only here. Male or Female...there is no third sex in our species. So nobody is excluded.Sticking to boys and girls creates an exclusive environment wherein some people are not included.
Regarding emotional gender, see below.
I don't think the problem is in how you address people, it's in how you allow them to express themselves. To use an old cliche example, if a little boy wants to play with Barbie dolls...why not let him? If you create an environment where children are allowed to acknowledge what they see with their own two eyes WITHOUT being to forced to conform to a specific identity, then that would be best for everyone. One can create an inclusive environment without censoring oneself from addressing someone as Young Man or Young Lady.Moving to they or using gender neutral terms when creating groups makes for an inclusive environment where you will miss nobody no matter who they are or how they choose to identify.
