All arguments about definitions are about what words should mean to best serve us. All ideas work this way, especially scientific ideas. They're all just tools, not objective or stable forms that we discover. The line between scientifically validated understandings and pseudoscience isn't sacred, but constantly in flux. This isn't a fault of science, but its greatest strength. We only make progress by testing limits and attempting to falsify what we assume to be true.
Using science to exclude other kin from gender identity overestimates our knowledge. I don't personally think it's just a part of gender identity, but related to some other aspect of identity. At the same time, science is barely starting to understand gender, and currently knows almost nothing about nonbinary identities.
There is no scientific explanation for drag, so anything we come up with is total conjecture. As a result, we should just accept our ignorance for now and move on. Doing otherwise is denying the limits to our knowledge.
Marketing American products with American culture? It's not that bad all things considered. Enjoying this country's natural beauty on a Harley is a genuine vibe that exists here. American motorcycle culture isn't just a Hollywood creation, but a real thing.
It is still marketing, but it probably is true. I wouldn't doubt that a German dude could've genuinely experienced what he saw in movies and found a bunch of cool foods along the way. There are plenty of cool restaurants on the road, and when you're traveling long distances, finding cool places to eat is a big part of the experience. He probably enjoyed simple staples like maple syrup, which is delicious.
