If you could care less about anyone’s opinion, and you go out of your way to shut down any opinion that is not yours, why the hell should anyone care about what you have to say or your experiences? They are clearly not improving the human race or bringing the human experience forward in any manner. Re-read your own paragraphs and then explain why you have more right to an opinion than say, a newspaper columnist that writes opinions for a living (your own example). Look up the definition of social, and apply it to social media. Then look up the definition of racism and see where you fit in.
