In the Advanced RP Section, it states that "Focuses on longer posts, often with in-depth plots, character development and extensive settings/lore. Must make a dedicated effort to minimize typographical errors and to use good grammar. Generally two paragraphs, but usually longer." Not really what I'm going for.

I thought this was classified as Casual since it says "Enjoy writing at least a paragraph or two, character development, and some depth. Grammar and spelling are encouraged. Generally one paragraph (a few sentences) per post. See individual GM for RP specific standards." I believe I didn't step out of bounds from what was stated in the section description. But apparently, I did. I was straight forward and being honest. Not really the type to sugar coat my comments. Apparently, that came of as rude.

Yeah, most probably support what Gayspacerock and Starstreemer said.
