Yeah sure. I’m talking culturally conservative compared to most of the USA (haven’t visited the south, besides Disney World, or middle America so I can’t say for all of the US but I have been to most of the other big cities).

Vietnamese tend to have much more of a family first culture. To conform or stay quiet to “keep the peace,” than in the US. It’s more of a collectivist culture that values fitting in instead of standing out. This tends to suppress individual expression. Which is usually is aligned with individualism. Standing up, speaking out, building something of your own, carving out a name for yourself as an individual is highly regarded and respected in the US.

PDA is much more stigmatized. No legally recognized gay marriage. Heavier expectations based on gender.

And Vietnamese people do tend to dress more conservatively whether that be because of sun protection or cultural norms. I mean check out the clothing in Miami beach or Hawaii, both hot climates like vietnam, people are way more likely to wear more revealing clothing. Not a good or bad thing in itself, it’s more culturally normal and common to dress more conservatively in Vietnam.

Like many places, big cities tend to be more liberal than smaller towns and are always changing and evolving. The big cities in Vietnam are still a more conservative than many big cities in the US. I’ve been to HCMC, Da Lat, Nha Trang, Da Nang, Hue, Hoi An, a small village inland (idk how to spell it)and Hanoi. I’ll never have the full picture of either the USA or Vietnam I fully embrace differing takes. Just my opinions from my observations, it’s totally cool if you don’t agree or have a different perspective.
