Serious question: Why isn't religious hypocrisy used more often against the opponents to same sex marriage?

For the last couple months, I've been writing the occasional post - titled #Biblebuffet - indicating the hypocrisy of people who oppose same sex marriage for religious reasons.

If you use The Bible to oppose same sex marriage, don't forget to execute adulterers, people who work on Sundays, and any woman engaging in premarital sex. All of these edicts are stated in The Bible just as explicitly as opposition to same sex marriage, and oftentimes within the same book of the Bible.

I was going to write another post today, but instead, I just have a question:

Why is this argument not made more often?

When someone like Ted Cruz argues against same sex marriage on religious grounds, why don't his opponents ask him why he isn't also stoning those who work on Sunday?

Or at least attempting to reinstate the Blue laws, making it illegal to conduct business on Sunday?

This seems like a perfectly logical argument to make, but I never hear it. And as someone who has read The Bible from cover to cover three times, I assure you that I could continue to write #Biblebuffet posts for years without running out of bizarre edicts and inexplicable prohibitions contained within the text.

Why not highlight the hypocrisy of bigots who hide their bigotry behind a religious text filled with equally clear prohibitions that no sane person would ever follow?

Seriously, what am I missing?

I'm also stunned that no one brings up Jesus when it comes to same sex marriage, because a complete reading of the first four books of the New Testament - the section on Jesus's life on Earth - makes sit abundantly clear that he never treat homosexual men or women with the same hatred and prejudice as people like Ted Cruz do today.

The man who opposed so many things in the Old Testament by advising his followers to turn the other cheek and "love thy neighbor as yourself" (also stating that there is no commandment greater than this) would never support these bigots and their crusade against same sex marriage.

No one ever talks about this. They allow religious zealots to treat The Bible like a breakfast buffet, picking and choosing convenient sections while ignoring others in order to support their own bigotry without ever challenging this hypocrisy. 

I want to know why. Seriously. What am I missing?
