i do not mean to sound like a hippy who professes of a world without any violence or displeasure (as both of those things are necessary in moderation), but i would like to highlight the value of communication, understanding, and sympathy even in those who you may not think deserve it. you do not have to like everyone, but it is essential for cooperation that you understand them. whether we like it or not we are the neighbors of millions of people and we need to learn to adjust to our ever-changing environment, and that requires us to be just as flexible.
coming from someone who has historically been widely misunderstood (and who used to despise people as a whole), i am saying as a more tolerant person that it is the most important thing you can do for someone as well as yourself to be understanding. believe me, it takes a horrible toll on yourself to hold onto hate, especially for your fellow man.
