It seems like in the top caption you were calling out people for being against same sex marriage because the Bible (an objective standard) is against it.
Then in the bottom caption, it seems like you're implying their stance is dependent on their own behaviour (a subjective standard).
I was trying to point out the inconsistency between objective and subjective.
As an example, even a thief is allowed to say robbery is wrong. Because it is objectively wrong. The fact that he's also guilty doesn't change that.
