Your argument seems to be that if you say a post is xenophobic, your proof is that you say it's xenophobic.
I say your post is written in French.
Not at all. As I've said, the only way to prove or disprove a post is xenophobic is to see if it fits the definition of xenophobia. Someone's opinion of what constitutes xenophobia is irrelevant. The problem comes when a fruitloop like Zlatan posts something that is the dictionary definition of xenophobia and claims otherwise.
The post isn't written in French as the words aren't French.
