Not mIRC!!!
For me, culture, clearly.
Then level of education, but I know a fair bit of people respectful who did not finish school or uni, then it's hard to say... probably politics, then.... popularity (but there are a LOT of popular people who I despise), then... very hard to say now, all are very close, I'd say religion, but it's hard to say.
