This is a really interesting topic (Dionysus always comes up with good stuff
)
Schizo? No. That could pose a danger to my safety, if they're suffering from hallucinations and living in a reality that doesn't exist. Tourette's? No, and only because Tourette's is usually not controlled very well, even with meds.
I don't consider myself judgemental, and I definitely agree that everyone has their "weirdness" about them...all I will say is that I seriously dated someone who was depressed, and based on that I can't EVER imagine dating someone with a worse mental condition. Don't forget that depression is an illness, too.
