First, if race-specific dating sites aren't offensive to you (and to me, they ARE) then why not race-specific bars? Or race-specific public transport? But there are plenty of dating sites that are exclusively targeted to gay men or lesbian women. If you think that race segregating dating sites are bad, then what are dating sites that segregate on sexual orientation? Are they also bad? No, because dating is entirely a…
If one has a personal preference, that's OK to exercise passively, but holing yourself up in a segregated community is rather anachronistic. You clearly do not belong to any minority, because if you did, you would understand how incredibly nice it is to be in an environment where you're not. A lot of people that belong to a minority clearly see value in services that target their niche, and it's very difficult to exp…
Unless you're demographically perfect in some way, everyone belongs to a minority in some way or another. I'm a rare southerner in a northern town - I don't want to socialize with "other" southerners, because that has nothing to do with my identity. I don't see a need to fraternize with people who are "like" me, beyond sharing a language and them not being religious nutcases.
The niche dating sites we were discussing aren't discriminating, they're targeting a niche, and that has to be ok.
Even when they say things like "exclusively for black people" (e.g. http://allblackdating.com/)?
Some people likes blondes. Some people like brunettes. Some people like black hair. Is that bad?
You can exercise preferences within open systems. It doesn't require discriminatory silos. The concept of a dating site "exclusively for blondes" is as ridiculous as a dating site "exclusively for whites." If you have preferences (and, sure, we all do) you can filter and exercise those within larger, non discriminatory systems like OKCupid.
Some people like whites, some people like blacks, some people like asians. Is that bad? Is that racism?
Often. If I didn't want to hire an Asian because I didn't "like Asians", that would be racist. If I didn't like a particular Asian for some reason, that's not (necessarily) racist.
I understand that people might have preferences on the race of people they date, but closing their minds to even seeing people of other races come up on their dating site sends a bad signal.
