I don't see why you are so indignant. You said these engines are failures. I said that to me means you think they are poor engines. you say that is not what you mean't and I say I believe you. I am just trying to show I did not twist your words, but that I have made exact quotes.
To me to say the engines are failures is to say they are poor engines. So what does it matter if that is not what you mean't by that? That makes me a liar?
