As a speaker of lojban, I have to speak out. Lojban is not Ithkuil. Lojban isn't that complicated to speak, and most of the times on the forums, people are debating better ways to express sentences, not just because they're incorrect. Also, part of the lojbanic culture is to nag people if their grammar is incorrect. In English, most of the time, people may cringe or roll their eyes if they see someone saying something incorrectly, but it's considered polite in Lojban to correct someone's grammar. We also have a lot of beginners and new learners, so don't be too hard on them - they're just learning. There's a common misconception that logical = complicated, which is entirely not true. Lojban is in many places much simpler than English, and makes a lot more sense. I'll admit, there are a couple things which are more complicated, but lojban was built to be spoken by humans, and you don't have to be a genius to speak it. In short, it's logical - but not complicated!
