If you take the time to read my comments thoroughly, you will notice that I always spoke to your behavior, and not to you personally. There has been nothing wrong with my behavior, which has been tame compared to how a number of others in the industry react when encountering things that are wrong or even upon mere disagreement. My only fault is that I do not sugarcoat things, which is hardly a fault in a technical forum where facts and logic are valued.
By the way, having one’s foot in one’s mouth is an idiom meaning you said something wrong, which refers to behavior. It being obvious you are clueless is a reference to your writing, which again, refers to behavior. Saying you should apologize to people for wasting their time is similarly a reference to your behavior, and you invited that criticism by demanding an apology in broken English.
Unfortunately the Internet is full of people who are very confident about things they don't actually have a mastered understanding on. It's not necessarily worthwhile to invest time and effort into interacting with everyone who stated their opinions.
