He posts so much it's not something I've noticed. Going through a month of his posts, his crime stories are predominantly Greater Toronto Area; there are a couple stories about whites. Not to be a fart-smelling yuppie, but I don't focus on race unless it's relevant which sadly in recent times is forcibly becoming the case.

Even Obama recognized blacks are disproportionately involved in violent crime in the USA, so I don't consider it racist to have a discussion, or for there to be more stories. Unless StartedGivingBlood77 is overtly vilifying groups or making a habit of pushing that boundary I would ere on the side of free discussion. Maybe at best (or worse) you can make a case for more neutral, less provocative titles?

Anyways I wouldn't assume a motive, that's a thin line.
