It's 2024 and some people are gonna gatekeep that if you're not shoving cams in some bigwall granite, it's not climbing?
And then there's indoors vs. outdoors, with some dedicated outdoor climbers regarding anything done in a climbing gym as "not real climbing".
Most people don't take this literally, and it's generally considered to be a standing joke in climbing. Sadly, though, some people take it very seriously.
(Climbing rock without ropes may be more "pure" but is so dangerous that it should never be idolized.)
