Arr... Agreed with many of you guys.
Granted, I'm normally a paragraph RPer, but that's because I like to create a story and feel to my posts, and I do enjoy roleplaying with "literate" roleplayers.
But, that's not to say I judge someone's intelligence by the length or style of their roleplay, either. I often find myself having very fun random roleplays with those who use a semi-lit style or even beginning roleplayers.
Although, it does disappoint me when I see users getting terrified of making a single error in their post, or making a two-line post a putting a "-sssssss-" (meaning 'short' or 'short-post' apologetically) because they feel they're inadequate if they don't make their posts 4 or 5 paragraphs long. It's ridiculous, and a result of some floofs being too judgmental with what they consider to be appropriate.
After all, there is always something to be said about a concise (not 'short) post, especially when the RP becomes fast-paced and you don't want to have enough time to go outside, get lunch, and also stop for a haircut before your friend finishes replying.
This said, I agree with you. If someone wants a 'strictly literate' RP, then that's fine, and chances are those who join will be very skilled in their style. But, seeing anyone who does something different as unintelligent or inadequate is really quite misguided and creates the opposite of a happy roleplay environment.
