Interesting question.
For acceptance, I think it just depends on which social circles you frequent. But for the most part we are moving to a lot more acceptance.
I spend time in a group that's mostly Asians and other Non-Caucasian people. There are several black men and women who are in the group with me. We were all attending a seminar. One of the sister schools attended as well. A very large black man was part of this sister group. I'm over 6' and he looked down at me. He is very personable, and has a white gf. No one gave them any looks or didn't smile at them or talk to them. They were accepted as part of the group. (as a cuck, I was very turned on because of their relationship though knowing how large he is and couldn't help myself from picturing them together doing the dance with no pants. Their relationship gave me a cuck high)
Conversely, I've been in other All-Caucasian groups where there is not the same level of acceptance, but there was no ridicule or ostracizing them from the group.
So, I think that things are getting better in the interracial realm and it's really not such a big deal anymore.
As for this site, it's a little different. Of course, there are just black men meeting white women here, but also it's a site where couples are connecting with Bulls. It's a place for bulls/wives/cucks to connect and share their interest in that kind of dynamic. Being a cuck-type I think that sites like this are needed because it's just not the same as a black man and white woman dating. How else can I get my gf to enjoy a hung black man
