>So, the same happens with American football, or baseball, or sports that are not widely followed elsewhere. Those types of conversations marginalize foreigners, even if it's non intentional.

And am I "marginalizing" someone if I want to talk about D&D, or retro gaming, or astrophysics, or some obscure musical genre?
