If someone doesn't agree with me, I'm okay with that. For example I made a post and a poster I was friends with commented about some information relating to my post, so I replied back and quoted the information from the article I was referencing and then the commenter blocked me. So honestly I'm just confused at this point. I'm a reasonable person, and I always, always man up to a mistake I make.
I just want to be given a chance like everyone else first. If you feel angered by people not agreeing with a point you've made, and you know the information to be true, then it's just something you have to accept. Not everyone will agree with you on everything, and that's okay.
I too have been in situations where I know the information to be correct, and was told I had to get clarification. The problem there was that the other person doesn't know information that I know (regarding computers) so they instantly go to, anything I do will suddenly mess stuff up, and once I got an answer I already knew and told the other person, then they were okay with it. And I explained to them, I've been using computers since I was 12. But because it's computers and servers at work, they only knew basic information and not technical information like I know.
