Maybe Bernardo didn't mean any harm with his "jokes" and just wanted to have some fun with his teammate, but sharing this with your 600k followers on twitter and 1,7M followers on Instagram shows that you are more than a little ignorant. Not being humble and apologize when confronted with it just shows us that he is just a complete jackass with a broken morale compass. It is a racist joke, not a hateful one, but racist none the less. Making a comparison of similarity based on skincolor alone is, making that comparison as a joke definitely is. The one he put on Instagram with him "joking" about Mendy being naked while wearing black clothes is in the same category. If he absolutely must tell racist jokes to Mendy, he should tell them directly to him, not through his 600k + 1,7M fans on social media. Then it definitely does not qualify as a joke among friends anymore. Being a sports star and/or a public person comes with some responsibility.
Try explaining to your kids (who follow him on twitter/Instagram) why these "jokes" are funny and tell them that sharing these kind of jokes in their social media channels are totally ok. I know I can't...
