I don't understand your extreme hatred of white people, tossip, as indicated by the emphasised text above. I don't want to go into expressing my opinion about your hatred because I want to avoid unpleasant discussion. I'm just curious about your motivation here: why do you think tennis "without Serena" will be worthless to all black people? Do you have any data (e.g. opinion polls) that support your statement? I doubt it because such opinion poll (segregating the subjects into races) would be highly illegal in US and most countries, but maybe you do have something? If you don't have anything official, and you base your opinion on your "feelings" or anecdotal stories, can you also elaborate?
Unless you elaborate your reasons, I don't understand you.
PS: For your record, in case you don't know me, I am a white male and a big fan of Serena & Venus in women tennis. So I feel sad that Serena lost her final today & in such a bad style but I wish that she wins in 2019 & improves her on court behaviour at the same time. But I will be even sadder when she retires. I think my sentiments are similar to yours up to this point. But unlike you, I think tennis does not end here: other players will come and fill in the void. Whoever climbs to the top of women's game and replaces Serena (it could be e.g .Osaka) will be judged by her tennis skills and not by her race. And even fans like yourself who hate white players, will continue to come because they will be cheering Osaka.
