I guess for me, I've found it's especially tough being authentic with family members. But when it comes to religion, I've decided to play along with them. I choose to be inauthentic with them because I think I'm better off in the long-run. I'd rather be on good terms with them, yet annoyed at times by their clashing opinions, rather than be estranged or have them trying to reconvert me, lol. There's a price to pay for being authentic and inauthentic.
