Yeah, it was a pretty lame comeback. And your definition of "melting" is pretty broad. If anyone sounds like an unhinged loon in this thread it's you. And you also look like you are literally melting.
You can call me dumb all you like, but even you know it's not true. I'm obviously a bright guy and that whole paragraph basically just amounts to the frustrated ramblings of an impotent keysmasher. But, ooh wait! You said I'm too dumb to realize how dumb I am. Guess the fact that some creepy, old perv I'm arguing with on the internet didn't convince me I'm stupid by calling me stupid proves that, right? 
And I didn't avoid any question. Just as you are entitled to gloss over whatever you see fit and respond to whatever you think is relevant, so am I. I corrected you when you misrepresented the guy who lost weight on a McDonald's diet and I also corrected you when you tried to conflate your very specific claim that "McDoubles are nutritious" with a broader "you can eat a nutritious diet at mcdonalds". If you need further clarification, if you define "nutritious" as food containing nutrients that will keep you from dying, then yes, McDoubles are nutritious. If you use the more common definition- promoting good health- then they are not. And it is as simple as that. If a parent made McDoubles a regular, consistent part of their children's diet it would be detrimental to their health. It would put them at much greater risk of obesity and cardiovascular disease.
Also, this is a response to someone else, but it goes to a point I made earlier which, apparently, you are too smart to comprehend.
This only makes sense as a hard-and-fast rule when you are absurdly selective about what you consider moral behavior. You can find immoral behavior produced by any social system. You are just willing to gloss over what doesn't fit your agenda and highlight whatever suits it, which shows your complete lack of logic in the matter.
I saved you for last not because you are my favorite but because I want to spend less and less time with you as you truly are a stupid person and everything I say is beyond your realm of comprehension. You're like the kid who wants to participate in an economic discussion by asking, "Why don't we make all houses cost just a dollar?" "Ha, ha. Sure kid," as I pat you condescendingly on the head, "we'll get right to that. But just take a seat over there for a minute."
In fact, that's what makes you somewhat interesting. How does someone, without a mental disease, which I don't think you have, get so stupid? I surmise that because your stupidy is so profound that you had to be taught to be stupid. You had to work and develop your stupidity. Such can often be accomplished by going to some Liberal, Leftist University. You're mention of "environmental footprints" and "predatory advertising" leads me to that speculation.
I was intending to address your issues but just at this very moment decided not to bother. Your statement, "I'm obviously a bright guy..." was just too gut busting. Like I said before, you are so stupid that you really don't know how stupid you really are and therefore there's no hope to escaping your stupidity on your own.
But I will note that now you are changing your tune. First you make up your definition of nutritious as "promoting good health" as the common definition. No it's not. Where did you get that lame idea? I know, it's because you are stupid. Lets take the macro nutrient, carbohydrates. It's a nutrient by definition and therefore nutritious but it does not necessary follow that carbs per se promote good health. It may or may not. Depends how it is used or abused. Same with a vitamin, a micro nutrient. If you take too much this will not improve your health and is often detrimental. There was a recent study proving that too much fish oil can have detrimental effects.
And though you now agree, because I've forced you to by exposing your stupidity, that McDoubles have nutrition and that McDonald's is nutritious; you've now changed from not being able to maintain good health from eating at McDonalds to JUST eating McDoubles.
You lose again dummy.
Now try to get out of the claim that McDonald's, the number one most successful fast food chain in the country in 2014, beating out BK, Pizza Hut, Jack-in-the-Box, Carl's Jr, Papa Johns, Quiznos, KFC.... all fabulously successful chains in their own rights, is not run efficiently.
You might want to bow out of this thread gracefully and go be stupid somewhere else.
