There is a place in Halifax called North Preston it is an area where the descendants of slaves escaping the USA settled in Canada. There is a gang now operating today by some of the male descendants of these slaves called North Preston's finest. These black pimps pimp black girls, mulatto girls and white women today. That is their profession. Pimping. Each one of these females has to make one thousand us dollars per night each pimping night for this gang of pimps.
And in the UK South Asians are notorious for being pimps and South Asian fathers for killing those daughters who refuse to settle for an arranged marriage to men twice their age.
Yes people can take the bad behavior of a small % of a group and use that to stereotype an entire group.
