My first thoughts go out to Grants family. Incredibly sad news. Personally, I think it’s never a good thing to start theorizing online after a sudden death without knowing the facts. I am critical of the Qatar World Cup but I will look at this as a very tragic loss unless serious evidence were to emerge regarding unnatural causes of death.
However, I absolutely disagree on the racism part. Do you really think there would be conspiracy theories floating around if this were to happen in, say, Ghana or Singapore? I have relatives in Sengal and Indonesia, and both countries are predominantly Muslim. I doubt people would be as suspicious towards those countries. Indonesia maybe more so after the recent new legislation.
The reason is not the skin color or religion, it’s the non-democratic regime oppressing minorities combined with a history of intimidating or even murdering journalists in the gulf states. Do you really not see a difference there?
