Carelessness in posting makes our board look careless.
We have truth and right and clear thinking on our side.
But the socialist lefties have literacy on their side. Let's try to narrow the literacy gap.
Does it require too much effort?
How much does any of us value what we post?
More important than appearance is the effectiveness of the communication. For example, I do not read walls of text. If you can not be bothered to put effort into making your post easy to read, why should I put any effort into reading it?
Grammar, structure, convention, etc. are tools for improving communication. Readers rely on the cues they supply, mostly unconsciously, to aid their comprehension. If you can't, or won't provide those cues for me, you are thoughtless, and probably don't have anything of value to say.
