Actually, no one sin is greater than another, except blasphemy of the Holy Ghost. I would think you could add the below to your list of things that really tick God off.
There are six things the LORD hates, seven that are detestable to him: haughty eyes, a lying tongue, hands that shed innocent blood, a heart that devises wicked schemes, feet that are quick to rush into evil, a false witness who pours out lies and a person who stirs up conflict in the community.
Proverbs 6:16-19 NIV
In the KJV "detestable" is "abomination"
Now personally, "Abomination" sure sounds like "ObamaNation" to me.
