I don't really care what disparaging things someone else says about certain hobbies or something that I enjoy. What they say isn't going to make me enjoy it any less. And if they don't enjoy it, then they're just missing out.

Now Marvel is pretty much the biggest movie studio on the planet, with a film in the #1 spot of top grossing films, and #2 spot for number of movies in a franchise (second only to James bond).
While pinball isn't necessarily a direct comparison, just in the time I've been in the hobby, I've seen it explode in popularity. While the current world-wide crisis has put a damper on locations and a shows, it seems like the home market is still very healthy, especially with the addition of home game rentals.
Yes, there are some downsides in that pins are big, take up a lot of space, and that certain ones can be expensive, but the same could be said about the car hobby.
