I wouldn't worry, It's a really easy point to miss in all the shouting around this, but Antonio clearly says he does not condone what Zouma has done or think it is right, he is just making the point that he has experienced racism in football and others have and is the reaction similar?
Now you may think the reaction would be similar and that's fine, but Antonio also absolutely has the right to question it. That's all the point is, he is not saying supporting the cat is racist or criticizing Zouma for his actions is racist. He is not trying to excuse Zouma's actions, he is raising the point that quite a few PoC have raised in this thread now that racism might not get the same reaction s this from the general public.
As I said it is fair to disagree with this or agree with it, it is a grown up discussion, just one that lots of posters here either can't understand or don't want to understand
