To be honest, I'd need more information before having a proper opinion on it. I don't think calling a black woman a black sheep is inherently racist, but it all comes down to context, personal history etc etc. I just don't know and the only thing I watched from the night (at the time) was clips of Laura dancing with Tasha.
It seems that so much that we say in day-to-day can be construed as racist/hate speech and a lot of it I would never have even considered such before tiktok. I don't know if it falls under unconscious racism or if people sometimes are reaching. I don't know. I feel like the older I get, the less I know. All I do know is if I say something and someone else tells me it offends them, and I don't think they're a t, then all I can do is listen, apologise and try to do better going forward.
