There is a gay agenda in this country for sure and it will never stop until EVERYONE accepts homosexuality in all schools,all forms of religions and the church will by law perform gay marriages. That is how evil works and never tires until good overcomes it. So yes this decision has an affect on all of us. The PEOPLE spoke in California and the court dismissed it. We have 50 million children dead due to abortion and still counting,what and how those children could have had an effect on this world we will never know.
You don't limit people based upon some monolithic enemy. The court affirmed the right to liberty and personal autonomy. By fighting the "gay agenda" and everything homosexual you are tramping on the rights of individual taxpaying citizens and relegating them to second class. The amendment which will surely pass now will be the only one I know which restricts people and does not enforce their right to liberty and pursuit of happiness.
You can save the sermon on abortion for someone who needs to hear it. It's not analogous.
As for evil, find another way to fight it than to restrict liberty.
