How so? when you claim they are at the bottom of the food chain so to speakBlack people seem to be desperate to "race-mix". It is easier for them to do that, as opposed to actually building up their own race for a change.
When was the last time/how often do you have someone black trying to fk you?
Or are you basing this 'desperate' assumption on personal experience of you trying to fk blacks and succeeding?
More likely it is fantasy and you were rejected time and time again therefore you spew all this hate filled bullshit.
