"if "bigoted" ideas are delusional, shouldn't the fact that we have far more integration and exposure to different sub-cultures in sufficient time eliminate all bigotry"
I'm not sure if delusional is the right term - small minded might fit the bill a little better. So if it's due to mental laziness or an inherent dearth of mental ability, perhaps bigotry is difficult to abate without laws to protect minorities.
Nonetheless you ask a good question - with time and exposure can we eliminate bigotry? I hope so. But it's easy to invent new targets for ridicule: Emos, Hipsters, Rockabillies etc. They're not exactly unprivileged minorities, but it shows how easy it is to disparage someone because of their appearance and cultural differences.
