The problem is the wider context. I 100% agree that Bernardo meant nothing malicious by his tweet - but what about everyone else? There are racists and bigots in the world. How do you respond to some school kid using a similar meme, or the office bigot, targeting a black kid or black guy respectively. Because now they hide behind the justification that it's just a joke - look Bernardo Silva Did the exact same thing, and no one made anything of it. And now this behavior, however innoculous, is normalised. And then in a couple of months or a couple of years, the next controversy will arise, and the argument will be 'well this isn't so much different from Silva's tweet, why should we allow that and not this?". The waters become muddied,more gray areas. Racism thrives in the gray areas, few people are overtly racist nowadays, but not taking action, making a stance allows the boundaries of what we as a society consider acceptable to be pushed more and more. And that makes it shittier for everyone!
