Just thinking more about this, I think I'm more disturbed by the fact that PSG are ultimately owned by the Emir of Qatar.
This is a country in which homosexuality is illegal. I don't know what the punishment is, but I suspect it's harsh.
Is it not therefore disturbing that such an owner is happy for his players to display a relatively minor signal of support for LBGTQ+, while at the same time doing nothing to address the issue in his own country? Not only does it make a mockery of wearing the symbol, but it reduces it to nothing more than a branding exercise and a marketing excerise.
I don't support Gueye's position, but I do think some good can come from it, as I said before. The owner's action is beneath contempt.
