Waxit, some things....
1) Stop posting emotionally, and stop taking things personally. The idea is that we DISCUSS. When we discuss, we will, sooner or later, disagree. That's normal, and expected in a discussion forum. What do we do when people disagree with us? We don't declare we're right and they're wrong. We can BELIEVE that's true and hold convictions that's true, but our BELIEF that it's so doesn't change anything. There are plenty of people who BELIEVE in things like a flat earth, and that vpw was some super-believer, but their CONVICTION doesn't make it so (and they may be fanatical about that.) We can declare what we believe, just not that it's "obviously the truth" because it's not "obvious" if there's disagreement. We can try to present our "case" so that others will agree with us. We can also pay attention, because we may discover that someone else was right all along, and we may find that the truth was something else, even something we didn't WANT to believe. (I'm speaking from personal experience- I've had others come to agree with me, I've changed to match what I believe was actually the truth even if it reverses my position.)
2) Declaring something's true by fiat STILL doesn't work. In a DISCUSSION forum, we DISCUSS. We can present our case that something is true. Perhaps someone else will add something that makes it a stronger case. More often, they'll point out flaws. Those can be flaws of communication (you MEANT something but SAID something else), of fact (you explained the Greek word used here, but you named the wrong Greek word) , or other problems. These can be addressed, and result in either a stronger case, or the discovery that you can't answer the important questions and may be wrong.
3) Don't type angry. Rather than type angry, get up from the computer, and do something else. Come back in a few hours (or a day), when you can approach things calmly. Whenever I find someone's accusing a CALM poster of being angry, it's usually been because THEY were posting angry and didn't have anything logical to say to refute the other guy's point. So, accuse them of something and pretend you addressed some imaginary flaw in their "argument".
