Imma be honest, that's a really dumb way to look at it. In the end, CSS really doesn't matter, its only aesthetic. Its the contents of the post which are important, and most people couldn't care less about that either. There are plenty of people who don't use CSS at all and make really good posts, CSS is like something we add to our posts because we can and it makes it look nice, or improves the reading experience. If you don't have time to learn CSS, that is fine its not required, as long as you follow the PC rules, everything should be all gravy.
Nobody here is a "tough guy" and if there were, it certainly wouldn't be CSS that would show it. Maybe someone with an english degree might be one, but i'm certainly not that guy.
