Yes, it does matter. When you respond to a post, there are people looking for accurate information. You and JMOR have been misleading and/or factually incorrect, and that's being charitable.
Why don't you debate like an adult? Little kids argue to prove who is right. Adults argue to get the correct answer, which is really what is important here. Are you afraid to debate?
JMOR and I debated. I finally conceded that he was technically correct in order to satisfy a wordsmith, but that his description of valve action was very misleading for a novice. That was my ONLY point.
Now, we are supposed to accept everything you say as GOSPEL?
