I refuse to speculate on what causes gay guys to select partners. Some things are best left to someone else’s imagination.
That said I believe you are right statistically. Black on black & white on white crimes are high then mixed race incidents. In the end Black, White, Red, Yellow we are all people and can be violent. Statistics are good in planning but for an individual event fall short.
in ‘old school PC terms’, someone set the wrong parameter :/
