I am going to rant.
There was your warning. I know that people are bad not because they choose to be but because of the way they have been forced to live by society. The very way of life that stops them from seeing society for what it is, what a much better life they were entitled to in the first place.
Today I encountered asinine hostility. From a learned and knowledgeable person who would otherwise be the epitome of civility. When he/she saw that I was great, that my theory was the greatest thing that ever existed, that the only just way of treating me would be utter, complete submission, he/she chose to do the opposite. Insult me to the core, act worse than an animal, be utterly uncivilised. So even if you are 100% right, people will not accept you if they can choose not to; it is only force and fear that ever works. Their ego will not let them gave away credit to another person, unless that very ego tells them to submit in the interest of self-preservation.
