Knocking others down shows weakness. Building others up shows strength.

Being judgemental comes from a lack of happiness and love with one's self. That hole inside you cannot be filled by taking a chunk of someone else. You cannot build yourself up by knocking others down, nor can you build yourself up by mentally placing yourself as superior to others. No matter how you try to excuse your projection as being smarter or morally superior or whatnot, subconsciously you know you are projecting. Subconsciously you know that you're not fighting to help society, but to help your own self esteem at someone else's expense.

If people are factually wrong or being immoral, you cannot change their mind by attacking them. As I've been told for many years by my mentor, you cannot shove anything down anyone's throat without getting them to open their mouth first. You can only educate people by getting on the same level and doing it politely and respectfully. The root of all bigotry and (human caused) problems in the world is from people who need to feel like they're better than others to maintain their self esteem. So many people these days are looking so hard to be offended (or find misinformation) so they can take a stance of moral or intellectual superiority, that they twist and pick apart your words to accuse you of saying things you didn't. They think they are fighting toxicity but they are toxic projecting as well.

When you stop comparing yourself to others (as either above or beneath you) then you can become aware of your own toxicity, as well as talents and good qualities, and be able to work on yourself and give yourself the credit you deserve. When I learned how to do this, it was the first time ever in my life that I felt a sense of happiness and fulfillment.
