Ok, there's something not right here. In Canada, every province has protections against sexual orientation discrimination. She should be going to the human rights board of her province to get this addressed. If you look at the full set of emails, there is a whole story behind this:

As a final note, this college and instructor are the exception, not the rule. My aunt is a head nurse. Sexual orientation has nothing to do with nursing in her opinion. It's a person's ability and professionalism that matters.
