My mother is pretty liberal by my country's standards, but she is nonetheless religious and I knew deep down all her restrictions "just because" was due to religion. She think I "might get ideas". It occurred to me that religious people are prurient, or ironically dirty minded. Most kids and people don't give dirty meanings to things unless you taught them specifically.
I mean I'm kind of afraid of the world. This planet has earthquakes and volcanoes and pandemics and tsunamis and prions and cancer and war and landmines and maybe a big asteroid every billion years.
No reason not to enjoy everything we've got, of course. It's still the best home.
I can see things like LGTBQ+, your own body/sexuality, and alcohol depending on who you ask, but why yoga, the world, or coffee? Yes these things can be scary to some people, but certainly aren't things to be taught to be feared unless you are trying to create something similar to brainwashed slaves.
