Stay-at-home-moms aren't as outdated as you choose to believe. I promise you I know a ton of them, and they aren't a part of any wealthy group, and they are more than just white women. So, your statement "almost exclusively wealthy, white women" isn't even close to the truth.
Every soap watching person I know being a woman shows percentages. And that number is very much higher than "these 5 people I know." Just for the sake of math, let's just say that number is 5000 people. Let's say out of those 5000 people I know, 500 of them watch soaps (or reality shows, since that's what that demographic is supposedly going to, according to the link I posted). That means 10% of the people I know watch soaps. And while demographics change depending on area, that is still a percentage. Out of 5000 people, 500 watch soaps....10% of people watch soaps. That is in Tennessee. Maybe it's just my area. Maybe the next 5000 people down the road won't watch at all, and that will change the numbers, but that is still stats, and still facts.
And I find it hard to believe that the percentage of people I know/have met who are part of a certain demographic is that much different than the percentage of people in any other area who are a part of that same demographic. I am very well aware of all the different types of people in the world. Sure, there's a chance I could walk up to 5000 people, asking them all the same question, and get the exact same answer from those 5000 people, then walk up to another 5000 people from 500 miles away, asking them all that same question, but get 5000 totally different answers, but that's not very likely. You are likely to get the same percentages from the 2nd group as you got from the first group. It's just numbers.
You are also getting butthurt over semantics. Just because I didn't use "most" or "a lot" in my sentence, you took it word for word, assuming I am dumb enough to think literally every single woman in the world sits at home, doing nothing accept watching soaps. That's pretty ridiculous. I have faith that nobody is that ignorant.
