What an ignorant and stupid thing to say. How the hell is another culture going to influence them to change just because? This is how wars begin in the first place, when two cultures cannot get along as well and end fighting to overpower one or the other.
Some influences had to be forced in with war, you are currently seeing that shit right now with Russia and Ukraine, with the chinese who comitted genocide to the Uyghurs, the tension and hate between South Korea and North Korea, Europe and America being so picky and racist with immigration (which in itself shits a lot on your premise completely already), all the goddamn arabs and their like 7 different schools of religious thought that have spawned a lot of wars and terrorism amongst them for the past decades, all because of religious/cultural differences they cannot tolerate from eachother and you are pretty much telling us that "meh, just give them time, one will influence the other without violence" what the fuck?
Even us mexicans, sending a ton of poisoned drugs like fentanyl to America because it's easy profit and we hate the way they treat us; their imperialistic and overly-corrupt capitalistic nature that has influenced a bunch of us and we hate it, and the only way to react back is with violence, that's why narcos exist, because of the lack of opportunities America and our own corruption have caused. They're just lost people trying to survive, taking the "easy" way out and so on. America forced us to join their stupid War on Drugs, just so that they could fill their prisons with black people and hispanics you wrongfully accussed for possessing drugs, some of them planted by your own racist cops during their apprehensions. About 80% of american prisioners are black, it is not a coincidence, it's just slavery 2.0, the job of the children of all the racist slave owners and confederate fools that got to live and breed, teach their kids to be disgusting just like them and so on. And also, the weapons narcos use come from America; Mexico doesn't even have gun factories, not for the ones they use at all. America has caused us a lot of innocent deaths and damage, a lot; 9/11 is a Disney joke next to it, and it's pathetic to hear you come and say that they are "just influencing us through culture", really pathetic.
What's next? Will you pull out a "TL;DR lol" or not respond at all? Because that'd be the cherry on the top; people like you have pulled that one out a lot before, but it'd just show everyone that you cannot even read a few paragraphs, let alone care about History or people in general.
Instead of pulling out a cheap gaslight or ad hominem out of your ass without proving or explaining how or why, just show us that you mean what you are, that you are legit, because otherwise you are clearly the only fool here who has never ever read a single History book in his life or has even an ounce of common sense or logic, so fuck off and be a goddamn human being for once already
