TOI:
Your comment is plainly irresponsible. Perhaps, one could debate whether to ignore casual drinking. I would certainly be among the machmirim, but I could entertain debate on it. But drunkeness is never acceptable. The medical label for drunkeness is “intoxication”. Translating that back into spoken English, it refers to a state in which the person is poisoned. That is never acceptable morally or halachically, and deserves the strongest efforts to stop it. Getting drunk Friday night, even if at a simcha is abonimable. It is NOT oneg Shabbos, it is NOT simcha, and it NOT muttar. That is every bit a serious as other “ossur” things other boys do, regardless of the environment they choose to act out.
