No nation in the world is a mono-culture, and often times, people repeat statements they saw specific folk from other cultures make and assume they speak for their entire culture.
This is called a faulty generalization, or over-generalization, and is a logical fallacy.
Every culture has their majorities and minorities - just like neither Trump nor Biden speak for all Americans, the person who educates you about Native American, French, Russian, Indian or Ghanan culture might just happen to be someone with an ideology that their own countrymen would harshly disagree with.
Many people repeat statements that single people on Reddit make such as "actually, we people in Central/South America think the word Latinx is ridiculous and don't use it" completely uncritically, even though for this example, the word even originated within minority groups within those countries (although Latine is more widely accepted, on a tangent).
Similarly, when I read communities dedicated to learning my native language, German, I find a lot of questions by learners that are like "are there non-binary pronouns in German?" or "how do I use gender-neutral language?" and all of the answers basically being "no, it's ungrammatical, nobody uses those, you are ridiculing yourself, generic masculine is universally accepted". As a German, this is just a conservative world view; admittedly, held by a majority, but nonetheless not universal across Germans.
It's a similar problem to the "n-word pass" - just because some Black person told you they're not offended, it does not mean that other Black people agree with them or that they are even right. Just because some trans people tell you that they don't believe in gender does not mean that gender abolitionism is a central tenet of "transgenderism". Just because a bunch of Native Americans came together and say that "Redskins" is actually an inoffensive name that they're proud of, does not mean they speak for all Native Americans and can be used as a token - or vice versa.
Make sure that you always realize that all countries have progressives and conservatives, old and young people, people of fringe ideologies, queer people, people who disagree on social issues, and so on. Not all Muslims are homophobic or transphobic. Not all French people are stuck up about their language. Not all Americans are gun-toting rifle nuts; and even among those, not all of them are conservatives.
The world is infinitely complex. Don't give in to overgeneralization.
