They're serious about following the rules because their entire social and community structure stresses conformity. If you break the norms of the faith there are serious repercussions and you can lose your entire family, community, and support structure. When they're alone with others who aren't of the faith they are definitely far more lax. I've drank beer and even had chocolate with Mormons before lol.

The poophole loophole usually means something different. They say anal sex doesn't count as "losing your virginity." So they can have all the premarital sex they want, as long as it's in the pooper.

I’ll bet you could even get a Supreme Court justice to help with that maneuver.

It’s capillary action. It just rams straight into your bloodstream, no dilution or waiting to go through stomach. It’s fast and effective.

Alcohol gets absorbed by mucus membrane much faster than by going through your digestive tract. And your anus is lined with mucus membrane.
It was a craze a decade or so ago where I live, cause teenagers did that to get drunk without having their breath smell of alcohol, and some of them ended up in the ER.

Additionally to what others have said it's also quite dangerous. You can drink a fatal amount of alcohol but your body will generally puke before it absorbs enough to kill you.

Using this method (boofing), you don't have that defense, it's absorbed too quickly and your body doesn't generally shit itself to expel poison.

I see this so often now, I can't tell if people are honestly that dense or they're intentionally pretending to be. In the spirit of Fry and Andy Dwyer, I'm not sure I want to know the answer.

Religion in general is crazy

Honestly, I kinda love the whole "lawyering with God" thing that Jewish folks have going on. For any religion with restrictive beliefs, there will be adherents who will try to find loopholes. I've been lucky enough to have an upbringing almost completely free from religion (except for a year drinking hot chocolate at a Unitarian Universalist church, which is almost not religion), but I also grew up in a super Mormon part of Utah. I've spent my whole life as a bit of an outsider, seeing people pick and choose which rules to follow and try to discretely find and exploit every little loophole there is. I've always found the hypocrisy a bit unsettling.

I think I'd really prefer it if the Mormons took the same argumentative stance with their god. It would make the picking and choosing a bit less hypocritical (which might lead to more Mormons ditching some of their religion's shittiest and most regressive teachings), and there'd be a lot less shitty sneaking around.

My relatively limited contact with Jewish culture has painted a picture in which this kind of technicality is, in fact, part of the culture itself. It's great

Yeah, just like how black people were bad and the "children of Ham" or whatever. After the Civil Rights Movement, Morman God mysteriously changed his mind and said "black people are ok now".
