I think your confusing "wall of text" with being "wordy". It's not using excessive verbiage to explain your point or word count thats the problem. It's the never ending stream of consciousness essay with words spelled phonetically and a general lack of punctuation that make it hard for people to read.
Remember we aren't in your head, and although you may feel that a general appreciation for the english language in a typed medium should be an afterthought, it really shouldn't. You have the nerve to call people out for being assholes for not excepting your jargon that is extremely hard to understand but fail to concede that you could put some effort into your typing, by possibly proofreading. Hell, if you have to, type it in a word processing program first and run spell check and look at all those little "error squiggles", fix it, then copy and paste.
You are not talking to us on the street you are trying to communicate via the written word and you are extremely bad at it. That is the problem.
Nah....that is not it. We just think he is a complete idiot.
