First off, I doubt that many if any at all today can say their grandparents were slaves in America.  A generation is typically thirtyish years.  Too many years have gone by as in more than 150 years.  Second, your pronouncements suggesting those of color would have to work twice as hard are based on nothing.  You have no factual evidence. You are just telling us how you view things absent any connection to reality.  It is true and will always be true that people are more comfortable around people who are like themselves.  It's just the way we are.  But today, equal opportunity exists more than it ever has.  For today's young liberals to have "discovered" white privilege is hilarious.  What is more hilarious is that the complainers themselves do nothing to make things better.
