erik55,
One mistake you make is saying “there are two indisputable facts”. In fact, you should say that “there are THREE indisputable facts”.
Your two were:
1. there will always be many drunks in shul on simchas torah
2. there will always be laytzanus by mussuf after wards
If those two assumptions are “givens”, as you claim, the third “indisputable fact” is:
3. there will always be people who defend sheim shmayim and protest this unacceptable laytzanus
