I'm not sure exactly what black voters are thinking when they oppose gay marriage. Marriage does not play a very central role in the black community anyway, so why do they care? The only thing I can think is that they don't want the distraction of another civil rights group seeking attention and competing for influence.
Many blacks have a strong religious upbringing, espically in the South.
How many black people have your spoken to? EVER? Speak for yourself about marriage not playing a central role in the black community because there are a lot of black people married raising families just like everyone else. Except the liberal media and people like YOU want to believe whatever it is you believe about people. Some even post here on FR, but let me not interrupt your senior moment about people.
