Hey there @Glisten 🙂
Excellent point! Also very interested in exploring this along with you.
I am unsure whether values are the basis of boundaries, would be my short answer...however..
I have been around the unpleasantness of someone else having different values that do not align with my own (read: I have some people I know who are judgemental based on race, gender, age, etc), and in these instances I would become very adverse to staying in their company, and came away with a bad taste from the experience.
However, I have had reason to be around them again and again (read: you cant pick your relatives 🙃), and I got kind of fed up with being offended, is what I could boil it down to, without having a say in the matter (read: trying to open up a new point of view got me shut down or disregarded).
Because of this, I tried to approach my values differently...
Sometimes, my values are rigid and act as a boundary, when it comes to situations I have some control over, or can contribute to changes in. For instance, I value not being discriminated against, and if someone does do that, I will inform them that I didn't think what they said/did was appropriate (like the old wolf-whistle; I would say "I personally find it distasteful and it renders you [the person who whistled] into a singular object in breach of my values [values here is being used as a boundary] and you being viewed by me as acting inappropriately - maybe reconsider how you want women to view you as, instead of something malodorous we sometimes find on the heel of our collective Louboutin's when you initiate communication in a method we do not find appropriate" ..said in much more direct, critically unmistakable language, which is NSFW so I put it very politely here).
Sometimes, my values are not boundaries, but just ethical positions I hold intrinsically, that inform the way I behave towards myself and other peeps (like when enjoying the company of those I havent chosen to spend time with, when they openly use terms to describe others that I do not and would never use...In this instance, I maintain my values intrinsically; choosing to dismiss their starkly differing values as inconsequential to my own, and something that can be observed, but ultimately disregarded for what it is: a tool of direct antagonism or a (IMHO) poor choice of method to vent frustrations in other areas of life - which isn't really a value at all.
Given that conclusion, there isn't any residual tension and they can govern themselves and how they like to present themselves and be seen by the world, and I will also do the same in my own way (with my own values).
And I tend to keep in mind the old saying, regarding leading horses to water... 🙂
