This feels like a troll... but I'll bite because the answer is very simple. It's called being social. It's no different than discussing what TV series we are watching, or books we are reading or podcasts. This is a very valid and common and healthy way of socializing among your peers.
You don't personally have to engage in it, at all. That's fine, but I find it odd you feel uncomfortable that others are perfectly comfortable talking about it. Given the focus of this site is too often on what we are buying for equipment, socializing around music seems much more culturally important.
