Muhammad's ball, or: what Islam has done to the French National Team

I'm not sure I follow you. As far as I can tell Skybird did not say ONE religion-derogatory or racist thing in this post. He stated only facts.

I never said Sky said anything, I just noted that he has gone to the crackpot fringe to find views that match his own.

I, for one, agree with the article 100%:

So you think there are too many blacks on the team and its gonna end up with just black players?

If you became citizen of certain country and are given the honor to represent the country on any filed as part of national team. You should be PROUD of it.

Yet the blog slags off french people of french ancestry.
Besides which private and very public differences within teams and between players and staff are pretty normal even at national level.
As for some players not singing the anthem before kick off, look at most teams.
