I’ve been inspired by many of my rebbeim who would get drunk on purim; I saw the torah coming out of them, the simcha…chazal say you can see what a person really is from when they’re drunk, and you don’t need emunas chachamim to understand it.
Parents who had rebbeim who got drunk in front of their families and talmidim have no problem “letting” their kids go to such houses. I personally don’t get drunk on purim, but I love being around those who do. And you would too if you’d drop the “drunk is bad” preconceived notion.
