You are a troll because you did not bother to take the time to get even a basic understanding of the subject you are posting about. You just posted an idiotic opinion specifically to get a repsonse from the community of this board
What do you care what's my understanding is, I asked my questions here and people can answer, that's the idea of a forum as far as I know. You can open your new forum and ask people to take an exam before they are allowed to post.
I also can say you are a troll because you are an idiot, so?
