It's one thing to be upset at a specific instance of a celebrity expressing a horrible opinion. I'm totally down with that.

What was commenting on here was a wider remark that celebrities should just avoid making political comments in general. "He's a football player, he should just play football. Keep politics out of sports."

This is the part I find unfair. If Kanye West has an opinion on global warming, we shouldn't reject it by default. If it's harmful, we should criticize it proportionaly to the reach of his platform (so... A lot). And if the negative effects get out of hand, we should be educating people on getting their environmental information from reliable sources, not limiting Kanye's freedom of speech.
