I mean, I already believe in a lot of basic principles that would horrify a lot of people - free speech, freedom of religion, I don't care at all what someone's sexual orientation is, and so on.
So I don't see where this should stop us from trying to form principles as an alternative to arguing that something must be or must not be true because of what someone wrote down millennia ago.
Perhaps it's time to consider forming some fundamental principles and reasoning from them instead?
