So the old dude in the video is talking about how they don't get invited to non-white or not quite white events. Maybe if his group didn't exclude these people, they might be more willing to include them.
Gal. 328 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
Churches may be based around a culture or a language because of the commonality of how they communicate or their goal of ministering to a community, but if they are really loving as Christ loves, then they would not throw anyone out of their services. The Good Samaritan was of a different mixed ethnic group (Samaritan) from Jews, yet he was praised for his love, thus we have a Biblical example of Christian love crossing borders. I think this can be broadened to interracial Christian love.
Actually, I was just reading a short article and watching a couple videos about race earlier today, specifically black Hispanics. If a church is a Spanish language church aimed at the Hispanic community, then they would do the community a disservice to divide along racial lines because they would have to have two or three or four churches, black Hispanic, white Hispanic, Native American Hispanic, and assorted mixed race Hispanic. If it was a black church, then they would have to have one aimed at Hispanic blacks and one aimed at non-Hispanic blacks. If you call Hispanic a race and don't allow another, you deny others their racial identity or their cultural identity. And this leaves biracial people without a church. That means far more churches and far more division, and far less working together to share the good news with others. Though we are different parts, we are all one body of Christ. Even the early church fathers knew that disunity was a bad thing.
On a practical level, this could be difficult because different parts of the world divide races slightly differently. (Armenians are considered [West] Asian by some Scandinavians, but are white in the US by court decision).
