I haven’t noticed so much disagreement 
Libertarians prefer to localize policy making as much as possible. Imagine how much worse a federal ban on sugar / hate speech / drag queens would be than a neighborhood ban! If you localize the policy enough - preferably to the individual - then it’s unanimous and consensual, and enforcing it is not aggression at all.
Accordingly, libertarians will disagree more when discussing hyper local policies, or federal policies that are difficult to localize.
Anyway, on to your suggestion.
Are you proposing that we have a platform and pass a bylaw to ensure LPSF reps stick to it? I’m not sure if LPSF has its own platform. I think we might have had one, but scrapped it in favor of the LPCA platform instead? Starchild would know!
The platform of LP California is an excellent document of applied libertarianism. It took radical principled positions on issues, including ones especially relevant to Californians and controversial ones not covered by the national platform.
It’s a lot of work to draft and maintain a platform. If you think LPSF needs to have its own, I think we should probably start with LPCA’s.
And yeah, LPSF officers should never promote aggression, or say that their personal preferences are the official position of LPSF!
