Blackpeoplemeet.com- because stick with your own, and make sure that when you look at someone, if skin color isn't the ONLY thing you see, at least it's the first and most important thing you see.
Jdate.com, ChristianMingle, etc.- again, stick with your own. Limit your heart to people who already believe what you believe. Expanding your horizons to include other viewpoints is scary and stupid and scary. Stay in your bubble.
Most important- we were intended to stay within certain tribes- race and religion are only among the biggest ones. After all, without these limits, how the hell are we ever going to maintain bigotry, ignorance, and hate?
Some of the best life lessons come from musicals-
You've got to be taught to hate and fear,
You've got to be taught from year to year,
It's got to be drummed in your dear little ear,
You've got to be carefully taught.
You've got to be taught to be afraid
Of people whose eyes are oddly made,
And people whose skin is a diff'rent shade,
You've got to be carefully taught.
You've got to be taught before it's too late,
Before you are six or seven or eight,
To hate all the people your relatives hate,
You've got to be carefully taught!
