I too was never really approached by white men until I ventured into online dating and started hanging out with white people. From my personal experience at the end of the day men are men. However, there is definitely a difference in how a black man approaches a black woman and how a white man does. I've found that a black man has no problem walking up to a random female stranger and hitting on her. White men usually need an "in" before they try to kick some game. Without that "in" they can think you're really attractive but they won't do anything about it. That's why so many white men approach black women online. The whole point of the website is to get a date so that's the launch pad.
Also if you're hanging out in the presence of other white people it lowers their inhibitions because they see that you're obviously comfortable socializing in the same environment. Remember that people date who they're around. So if you're around white people, a white man will more likely conclude that you'd be open to date him. That's probably why they were more willing to put it out there in those circumstances.
No, not all white men are racist. I will say that many do try to overcompensate by talking about how much they love black people and that we're so cool and fun and blah blah blah. However, that's moreso an insecurity on their part. I actually find it very uncomfortable when a white guy starts gushing about how much he loves black people. Heck, I don't even love black people that much so I don't know why he does
. Yes, I will admit that a lot of white men have racial blind spots and can be ignorant. However that's usually from lack of interaction with people of other races. And honestly from a lot of the responses in this thread we display a similar type of ignorance when it comes to relating to them.
At the end of the day it's about attraction and comfort. If you never hang out with white people and are never approached by white men the whole "do you or do you not date white men" is pretty much a moot point.
