I know what you mean. People get far too emotional online. They are filled with rage. We could all learn to bite our tongues more often. If someone points out to me that I legitimately wronged them, I do my best to recognize it and apologize. People can take offense at the smallest things or even at nothing sometimes. Even today, I was demeaned for supporting Israel (which happens regularly because half the people are straight up anti-semitic, and 40% just don't care, and there is only 10% who actually care, and I digress!). I was even told I was wrong in no uncertain terms when the person didn't have a case, and then they said later that their telling me "You're wrong" was an actual argument for why I was wrong. People today are very sloppy thinkers. So often, people assume I am saying one thing when that is not at all what I am saying. Misunderstandings are very common online because we all have these hidden assumptions of "if they believe X, that automatically means they believe Y and Z as well." That is probably the most common problem I run into online. People shoot first and ask questions only when it has been proven they are wrong about me. We could save on a lot of disagreements if people just argued against what the person actually said instead of imagining what their position is. It's good for me to realize I could be wrong. It's also a good debating strategy not to guess and make stuff up on the fly. So many people think something is true, but they have not actually learned anything about it. They are just going based on their many teachers and are given to myths and legends. We should be quick to forgive and quick to be gentle with our response. We need to be patient and not emotionally charged. I believe anyone can learn how to do this. Just stop and ask yourself if you are responding in anger or not. If you are responding in anger, then think VERY carefully about whether what you are about to say is actually necessary.
