I believe that the primary reason for the poor behavior of people, not only here on MacRumors, but the Internet as a whole, stems, primarily, from the fact of online anonymity.
People are less afraid to say things online than they are in real life, directly to someone. Some people will say the same things in real life as they will online, whether good or bad. But I think the anonymity clause leans heavily in the favor of being of two personalities in most online discussions.
I am one of the people who are the same online as I am in real life. I am me, and I don't change that. If you were to meet me in person, I'd be just like you'd expect me to be as you've come to know me online here.
I feel its an absolute tragedy that some choose to be a more mean and spiteful person online because they have the advantage of anonymity. If someone is mean online and in real life, for shame. I don't understand, nor do I wish to know, why some people choose to be mean, trollish and overly spiteful towards others.
… respect others choices.
I think a lot of people don't understand the differences in opinions and facts a lot of times and then rant against others who display an opinion, thinking they meant it as a fact. There is too much subjectivity in reading and writing of posts. I do my best to look at posts, and real life situations, as objectively as I can. Since I made a conscience choice to do that, my life has been improved dramatically and I find myself not angry, less stressed and more happy.
Objectivity, to me, is a way of looking at things, situations, not just from my point of view, but from others as well. Being able to see something from their point of view helps me understand how or why something is, or why a person chose differently from me. That helps me better accept things, whether I would have agreed with, done or picked that thing or not.
