You think a shirt determines his preferred system of economics? Is this like who you take a picture with determines a persons politics?
You guys are hysterical.
So if you go by a photograph he is a Muslim terrorist, his shirt a communist. What if he wore the shirt in the picture, a Muslim Communist? That would really have you fools shitting in your pants.
Look man, the estimate of the number of people who died in the Soviet Union is between 60 million to 100 million people. That's not counting the number that died under Mao and Castro.
So forgive us if some of us think its offensive to wear a Castro shirt, or a hammer&sickle shirt, or to espouse the same political ideals that got hundreds of millions killed in the name of "social justice". It's just as offensive as wearing a shirt with a swastika.
I'm not saying social justice is always bad. I'm saying there's good reason to be distrustful of it.
As for the muslim thing, I've got nothing against muslims. I have a lot against fundamentalist muslims who advocate for sharia, which Linda Sarsour does. Any western liberal should have a big problem with fundamentalist islam because it's inherently illiberal and incompatible with western values. Kaepernick espouses too many radical leftist ideals and rubs elbows with too many fundamentalist muslims for my liking. Call me racist for that if you want, I just say that makes me a principled liberal.
