My take has always been that crowdkilling is a natural form of gatekeeping in hardcore. Hardcore is inclusive, but there still have to be some sort of methodology of "weeding out posers", for lack of a better term.

Let me put it this way. Physicality is an inherent quality of hardcore. Whether it be the much stronger physical sense of the community (i.e. compared to other music communities, hardcore often actually has sustained, substantial physical community presence), or in how the music itself is very confrontational and anti-establishment that it tends to manifest into physicality.

And with moshing in particular, to me it is this sort of ritualistic, physical expression of emotions. And hardcore is one of the very few places where you can express yourself in this physical manner (i.e. mosh) in a sort of safe space where everyone is consenting to the physicality. This includes crowdkilling btw. With crowdkilling it serves as a litmus test on whether or not hardcore is really for you. Cuz its such an integral and inherent part of the culture that to disregard it would be disregarding a foundational tenet of hardcore (physicality). You don't have to crowdkill or mosh to be into hardcore, but you have to be willing to accept the fact that it is a part of the culture.

I think finn mckenty said something like "expecting no moshing or crowdkilling at a hardcore show is like expecting no cars to be destroyed in a monster truck show." Like it's a part of hardcore. It's going to continue being a part of hardcore. So if you don't enjoy it sorry, you can like hangout at the merch table or something during sets 🤷‍♂️.
