I agree. The letter writer is complaining about how private companies deal with racists. If Twitter doesn't want jerks harassing people with racist comments of the "you're an ape" variety, that is their right. And if people want a festering, racist social media platform, they can make one and hope companies will advertise on it to pay the bills. But I find laughable that people feel free to post horrible things and then sob, "Don't be so PC" when others rightfully label them as jerks and tell them so. They gotta grow up and take it like they give it!
