Drinking alcohol is almost certainly more dangerous than dropping hats.

This is not even close.

Heck, pick any one negative impact of drinking alcohol at parties (impaired driving, or long term health effects, or impaired judgment, etc) and that individual impact would probably be orders of magnitude worse than the total negative impact of dropping hats.

If someone spikes the punch with alcohol that's bad. If everyone is consenting: drop away. If they don't consent please leave them alone.
