I disagree. Just as I would not put "I have migraines" on my soon-to-be-created online dating profile, I would not put "I am bipolar". What is the difference? Both are brain disorders, both are treatable and I receive treatment... why is it a potential partner's business? Back to the "need-to-know" principle: if I happen to have a migraine that requires that I cancel a date, then of course I will say "sorry I have a bad migraine" because it is relevant. Otherwise, it is not relevant.
