So...tolerance is something we are encouraged to practice in all aspects of our lives. I guess it depends on definitions and such, and I really do not want to get in to semantics, but tolerance does not work for me. There is a connotation in the word tolerance that bugs me...it is kind of "well I do not agree with you but I will tolerate you".
There is another word that I prefer and one that I try to practice in my life - acceptance. Acceptance to me means "well I don't agree with you but I accept that is your point of view".
None of us have had the same life experiences. It is those life experiences that make us who we are and shape what we do, what we say, what we think and what we believe. When I am talking with people and they tell me things, I try to relate to them in terms of my own experiences, but I can never fully appreciate their perspective because I am not them. So I accept what they tell me as being true and valid for them - because it is, no matter how alien it may seem to me. Even if I do not agree with them, I will continue to discuss things to help me try to understand them and hopefully show an interest in that person despite our differences.
I really hate the attitude of "you are wrong". There is someone I have to interact with in SL as part of a role play I am involved in. His behaviour suggests his firm belief that he is right and therefore any difference of opinion is wrong, but he will tolerate your presence as one would tolerate any other annoyance - but he has to speak out about it. He seems incapable of accepting that people have their own points of view and their own interests. It makes him very hard to deal with, but you know what? I accept that is him.
