A business needs to have the freedom to kick out shitheads so as to protect itself from becoming a place that non-shitheads don't want to do business with.

A grocery store doesn't let people walk around in their store saying just anything to their customers. They're (rightfully) not bound by as high of a standard for what they allow to be said in their store as the government's standard for how much they'll let you say before they imprison you.

You could say the same thing about a telephone company or a postal service. After all, they are just like a grocery store, so no need for them to uphold free speech.
