"Stupid" though is often dismissive, the reason my eldest relatives refer to homosexual people as "The gays" and believe marriage should be between a man and a women, is because they come from a different time period when these things were not only socially acceptable, but practically the only way to think. It's sad that they have not grown to feel differently in the face of society, but that's "stubbornness", not stupidity.
If someone believes vaccines cause autism and so refuse to get their child vaccinated, despite all the research proving otherwise, that's "ignorance" not stupidity.
I'm not saying these people get a pass for their behavior, I'm just saying it's not due to a genuine lack of intelligence.
That being said, I have the capacity and have also in my life have done things that other people would consider stupid (particularly when driving, really just stay away from me on the road), but if I do something stupid, I feel genuine remorse for it and usually apologize. I've found the older I get, the less I really know (and have become almost afraid of weighing into controversial subjects because I admit that I don't know much about them) and instead usually opt to understand why someone has taken the stance they have, rather than trying to change their opinion.
So OP, to answer your question, no, I suppose there aren't many "stupid" people anymore, they have been reclassified to more accurate terminology.

If you think there's no stupid people, clearly you've never spent time working in the Retail or Customer Support Industries.
I didn't often think customers were stupid as much as they were lazy or ignorant [footnote]There's a giant sign that says "Kids" right in the middle of the store that is viewable from the door and they ask me if I sell kids shoes.[/footnote] For what the difference is worth, or inconsiderate. I do think everyone should be required to work at least two years in one of these jobs as since then, I try to be mindful of things such as store hours and signage, and if I'm getting angry in line, I tend to get angry at the asshole giving the cashier a hard time, rather than the cashier for not getting to my order quick enough (because they're busy dealing with the asshole).
