The "learn a language before traveling" always seemed like gatekeeping to me. I've traveled a decent bit, and I would not have had the time to learn a dozen or so languages. Especially when you have to learn entire new writing systems. I'll learn a little bit while I'm visiting because I'm immersing myself.

if someone wants to study another language, all power to them. But it shouldn't be a barrier from experiencing other cultures.

So you'd be cool with people doing this in Spanish on Texas and Florida beaches right? And I mean people should definitely never travel to a foreign place without a decent grasp of the local language. Not like world exploration is something that can be a life altering experience. Or could help people empathize with different types of culture. Nope. Everyone should stay in their own little bubble. And honestly that applies to states, districts, etc. Hell even towns. Because Alabama and California are super different and have different customs. But even Houston and Austin Texas are way too different to go into each other's areas without having a firm grasp on local customs. Barcelona and Aragon are so very different that many of them don't even speak the same language. One of my neighbors and I don't get along real well. Perhaps we should really only stay in our houses.

Amazing amount of strawmans saying they need to learn the entire language and not a small amount of it, as you clearly stated.
