Let's apply your declaration of labels as meaningless is arbitrary to another situation:
Surely you don't spend your time convincing women that the difference between consensual and forcible sex is a void label? That the concept of consent is a futile attempt to manifest an utter and complete abstraction with no inherent value or meaning.
Would you insist that it doesn't matter if a woman -- clinging to the delusion that consent matters -- might be offended when you act on your conviction that consent is an illusion. Circumstances and context are irrelevant, after all!
No. You would be a sociopath or worse, for pretending that a meaningful abstract act -- consent -- is meaningless because you can't understand it or are inconvenienced by it.
Your entire argument is flawed by fallacious and/or bad reasoning. Based on what you've written, it's obvious that you've never been significantly hurt or impacted by racial discrimination. Consider, then, that you are greatly unqualified to be dictating to anyone the nature of such experiences. The authority with which you deign to define racism -- or dismiss it as non-existent -- is astounding.
