My main concern with your question of whether we attend Black events or Black clubs is... I'm white. If an event or club says "we're for black people", I'm going to respect that. I mean, they don't need me crashing their party. Once again, I've never encountered one (and I asked around my black friends and they're not aware of them either. Could it be a US thing?), but I've seen that with, say, male-only events or single events or family events.
If an event is organised for a group I'm not a part of, I'll stay out of it out of respect, not because I'm close-minded.
