Women have a saying: "sometimes it's easier to give than to explain why you can't." The same applies here. Write, sir, and your reader will be found.
When a person can't explain something, it's usually because they're too lazy. Most likely, they either have nothing to explain, or their explanation is complete nonsense. But everyone has the right to express their opinion about this situation. I just wanted to say that Vitaly is 100% right, so you don't feel offended or defeated in an unfair fight. Even though I'm a noob, I can still express my opinion.
