I've rarely, if ever, suggested someone provide a hand check as I'm not trying to put my pork sausage fingers on display. In fact I've rarely labeled anyone suspect, however it serves its purpose if the pictures are accurate. It let's you know if someone is a white guy sowing discord, a white person basing their opinions on stereotypes vs real world experience with black people, a black person with a fucked up mentality, or someone so removed from regular black folks that classism is coming into play. Some folks are worth debating and engaging in dialogue, others aren't. Knowing someone's background helps me make that decision.
