The government can't tell religious orgs what to do (within reason). Religious doctrine cannot be used to craft government policy.
This is an absurd standard and it's horrifying that liberals seem to have internalized it.
What specifically do you object to? Why should others be able to force their religious beliefs down our throat by legislating it?
For the standard to be juridically enforceable there would need to be an objective yardstick for when a policy position is inherently religious versus when it simply happens to correlate strongly with certain religious commitments (as opposition to abortion does with Catholicism, or GMO skepticism does with various "granola" New Age and pagan currents). I don't think developing that yardstick and giving it the force of constitutional law is either possible or desirable, and I assume Xahar doesn't either.
If religious doctrine inspires lawmakers to enshrine those values into law, it is by definition, forcing their religious beliefs on everyone else. That should not be acceptable in a liberal democracy.
This is obviously absurd cause everyone will have some sort of a basis behind their philosophical and moral beliefs and for many people that is religion.
The appropriate standard for this is whether a religious justification is the
only type of justification you can make for a certain policy and if thats the case then I would say it violates the principle, otherwise it does not.
