Is yelling and getting upset a common thing in raiding?

I’ve been raiding with the same guild since Vanilla. We get AOTC every season. Our guild leader is known for getting upset and yelling people over discord when things don’t go as planned during raid. I get frustrated and find myself often asking if it’s worth it. I don’t really want to go looking for greener grass, but I am curious: is this common behavior amongst guilds that push heroic or mythic raid progression?
