You make a lot of assumptions there though, don't you? You're assuming that you would be motivated to "return the favor," but where does that motivation come from? Humans reciprocal acts are learned traits. There's nothing they get in return for that act alone. The return only comes from the potential impact on the community, which is a social function, not biological.
I used lions as a contrast specifically because they're behavior is different. They are baser creatures who's community does come directly from biology and it's drastically different. I also also gave canines as an example because they are specifically social animals and those behaviors that are similar to ours are derived from the social aspect, not biological since it's community specific, not species.
Sociology studies how humans behave as groups in relation to each other. It's specifically about the things you're describing. Evolution drives us to pass our genes on. That's it. What you're saying can be just as easily used to trace literally everything humans do back to evolution. The argument could just as easily be made that religion is a result of evolution. Humans are curious because looking for answers gave us a cognitive advantage over competition. That trait leads us to searching for answers. If none are available, we find one. And now we have gods. But religion is organized and requires groups, which brings us back to sociology again.
So I work with a lot of people from a variety of countries. Some of those countries have really bad governments. When we joke about each other's countries, it's about the governments. I remember this guy who used to work with me from the Philippines. It was near the beginning of lockdowns and just after Duterte was elected. He made fun of the shit Trump was saying and doing, and I got to joke that they had their own Trump(maybe worse) coming. Australian co-workers laugh along when we joke about their shit politicians.
What we don't do is joke about the people or the culture. That's shitty. All those people are just as much victims of their own circumstances as we all are of our own. But we're adults who work with each other every day and it's easy to remember that we're all real people. The internet however...
I haven't noticed Americans getting upset when people criticize shitty government policies or decisions. At least not from people who aren't boot-lickers from jump. The problem is when people make fun of American stereotypes. Americans are fat and loud and whatever. Like, if all you heard was people talking about Canadians being stuck up about needing things written in French or topped with poutine, it would probably get old, right? "Go cry at your Tim Horton's and take your polar bear for a walk." (okay, so I had to google Canadian stereotypes and it's a short list.)
I don't like America's gun culture either. And I hate when it comes up there's always someone who comes in and preaches the gospel of the 2nd amendment. It also doesn't feel great when people make that generalization about me. This thread is full of people saying Americans are dumb and racist. That's just shitty behavior that no one bats an eye at because it's normal to make those jokes. If I started making comments about like, French people smelling bad or (insert some other offensive thing. I don't keep track of bad stereotypes and I'm done googling it) then that would also be bad and it's a thing I think we should start calling out across the board.
