Disagree. The reason there are no popular white-focused dating sites is because they would be hounded or sued out of business! It's "racist" for white people to congregate on a race-dependent basis, but acceptable for people of other races. I guess it's our payback for our ancestors being idiots in the distant past.
That said, I think racial segregation is a "problem" (though it's not always "racist", per se). The existence of dating sites exclusively for certain races is the issue here.
We need to go one way or the other. We ignore race and discourage its use as a demographic tool, or we celebrate it and allow people to silo as they see fit. Our society seems to have mostly chosen to ignore race and consider it a non-issue, so "Blacksinglesconnection" or "EliteNoire" (Are you shitting me? This really exists?) should be as distasteful to our society as a hypothetical "Whitesinglesconnection" would be.
