What nationality would you never date?
I would never date full French, full Italian or French-Italian women for example.
There are other nationalities and "combos" I'd never date or even be friends with, given that I've seen of those people here teached me to keep a wide berth.
What about you?

Reminder that this question is not aimed towards devaluing or valuing any group in particular.
I myself don't take it personally if you answer you don't want to date Italian, French or Italian-French guys.
It's just preference.
