edit: to offer a slightly more substantive reply I will offer the Merriam Webster definition of cooking, which is "to prepare food for eating by a heating process" which applies just as much to warming preprepared or frozen foods as it does to enthusiast home cooks. I agree with you that the class divide is exemplified by the extremes of rich idiots who can just order Doordash for every meal and people who rely on the grocery store freezer section. The difference is that the people in the grocery store freezer section are actually cooking their food, while the Doordash people aren't, and the former category of people is substantially larger than the latter.
