And so you just crushed the idea that simply accusing someone of being racist wins in a court of law.
When you explain that you didn't invite him b/c he is a c0ck-blocker, then you show it was not a racist act. It was in order to avoid the likelihood of him ruining the expected nights activity.
As soon as the sole reason is the color of his skin, or ethnic heritage, it becomes a racist act.
Kind of like when a company hires the less-qualified person over the more qualified person, when the only difference between the two is the color of their skin..
Tons of court cases decided based on evidence and proof of racist actions taken against people. Tons of them for the plaintiff, tons of them for the defendant.
