Let's see if I got this right.
You are saying that you write your posts to state what you mean to say. If we have a problem with what you post, we are to assume that you actually agree with our position and what you actually posted is just a poor choice of words on your part. We are to assume that you do not mean what you wrote and ask you if you really mean what you posted. Does that also mean that we are to ask you if you really mean those statements that we agree with. It is a double-edges blade that cuts both ways. We have to accept everything your post states, or none of it. We should not have to pick you post apart to determine whether you meant what you wrote.
On the other side of the coin, you hold all of us accountable for what we write. You expect all of us to select the appropriate words to convey our beliefs. You are not reluctant to express disagreement with what we write. Once again, that blade cuts both ways. Since you hold us accountable, then you should be accountable.
I, for one, NEVER submit my forum posts for editing, thus I'll often use the incorrect word when responding in heat (what a scary thought!). Generally, it's best to keep the general theme of the message in mind before jumping on a single word used. Very often, it was used inadvertently.
None of us submit our posts for editing. I can't speak for others, but I typically read what I write before posting it. If the wording doesn't mean what I want it to mean, I rewrite it. It is called being accountable for what you say before you say it.
I and others do keep the general theme of the message in mind. When the general theme says one thing and one or two words seem inappropriate, I assume it was a poor word choice and ignore it. However, when the word choices fit the general theme and I disagree with what is said, I comment on it. I will often pick out specific words and phrases, but it is the overall message that I have a problem with.
... something you never convince anyone else with because no one is confused by your deceptions.
See that is part of the problem. We tell you what we believe. You assumption is everyone should agree with you and your positions. You want all of us to accept your statements as accurate reflections of what you believe. You seem to have a problem believing that someone might disagree with what you say, so if someone disagrees, they must be trying to deceive others. Evidently, you chose to deny that some of us are really saying what we believe.
If you stop looking for specific words to object to, or even just ask if I really intended to use that phrase, we'd waste a LOT less time in pointless, endless arguments.
If you were to take a few moments to read what you write and correct any misstatements, as you said, we'd waste a LOT less time in pointless, endless arguments.
