I know where this reaction comes from, being imposed about a certain culture doesn't sit well for cypherpunks/bitcoiners. However, seed oils are bad for you and there's scientific evidence that they contribute to heart disease. It just isn't talked about because of incentives. It is another rabbit hole in itself but here's a pretty good overview to start: https://openheart.bmj.com/content/5/2/e000898

There's definitely a lot bullshit in the world, but avoiding seed oils isn't part of that. 

 i don't understand the phrase "being imposed about" ... what do you mean? 

 Being forcefed something. Insisting to others that your lifestyle is superior.
