Why do public displays of affection differ between interracial and intraracial couples? Why do they differ?

I never noticed that they did.:confused: I think it is all about the people and what they prefer, not the race.

Unless of course there is a religious factor.

I don't believe they do, between nations and customs in those countries there are various culture customs by they have nothing to do really with race.

And if anything there is more perhaps within the same society for social economic groups than racial

That's a huge generalization.

My guess is that you have something specific on your mind?

Why does this bother you anyway?
