<p>Sexual orientation is not really verifiable by an outside source, whereas race is determined by your ancestry. Typically schools have cut-offs (25% or something like that) to determine minority status. Even though they rely on the student to be honest, they could hypothetically kick a student out for lying on a student application about it. In contrast, there is no way a school could verify who you are attracted to.</p>
