If 97% if the population can’t cook then why was there a shortage of flour in the first lockdown? Was that caused by 3% of the population? didn’t you know? They were buying it to make home-made playdough. 
Cooking is all subjective. I don’t consider putting a ready meal in the oven as “being able to cook,” and neither do I understand how anyone can live on ready meals or takeaways, but equally every meal doesn’t have to be like something out of the master chef kitchen e.g. pheasant with duck egg - fine as a one off but a bit pretentious if you expect everyone to eat like that all the time.
There is and should be middle ground. I do cook everything from scratch because it’s how I’ve always been, and more latterly I have a serious heart condition which means I have to be careful about my salt intake, and the more processed a food is, the more preservatives and chemicals it contains.
But equally the jar made sauce has a place, e.g. stir-fry sauces. I make my own teriyaki but I have the time to do it. But not everyone does. Making your own sauce in that instance is the difference between coming home, having to make the sauce and only then starting the dinner, and coming home and having dinner on the table in 10 minutes.
And maybe some people actually enjoy certain processed foods, I buy the young’s chip shop fillets because I actually like them. I make my own oven chips, but I’m damned if I’m going to mess about with batter and hot oil and deep frying when I can stick a couple of fillets on a baking tray in the oven.
Just because you don’t like certain curries doesn’t make you wrong. Avocado makes me want to throw up, that’s before I take into account the fact that it’s contra-indicated with one of my meds. But if I started a thread saying “I think that people who eat avocado are incredibly sad because they don’t realise how horrible it really tastes,” I would look like a judgemental twat.
Eat what you eat. Enjoy it, and let other people do the same.
And if you have to admit you’re a twat in real life perhaps you should work on that.
Personally I think it’s sad that anyone can be quite so condescending, in fact that’s worse than not being able to cook, because if you’re not careful your attitude will mean you’re left eating that lovely cooked food on your own.
