The quickest way to a backlash against gay marriage ruling would be attacks on religious liberty
Liberals attacks on religious faith have only accelerated under the Obama administration. From Obamacare's attempt to force people to violate their conscience on abortion to the attempts by some jurisdictions to punish and put out of business those who do not want to participate in a gay wedding their is an ongoing attack on faith by the secular progressive left. It that continues this country is likely to see a huge backlash against these attacks and the dicta in Justice Kennedy's gay marriage ruling may not be enough to stop the attacks.
The governors of Texas and Louisiana were among those calling for stronger legal protections for individuals, businesses and religious-affiliated institutions that object to same-sex marriage.
