But your idea of freedom is in human terms only, and does not take into account what God designed as True Freedom in Christ.
But do we or should we have the right to use law to impose restrictions on people that are purely religious in nature? Murder, rape, theft of property, and all similar things directly and negatively impact another humans life which we have no right to do. Therefore we restrict such things by law. But what two grown people do sexually or whether two people want to be legally bound to each other in no way affects me or my rights. That being the case on what legal grounds can I say it should be illegal?
On what basis do we have no right to negatively impact another humans life by such things including murder, rape, theft, and others? Are not these restrictions based on something?
You do not want our laws and restrictions to be based on religion. Well any moral laws are based on God's nature and His natural law, along with his Word.
So what reasons do you based the "approved" restrictions? From what source tells you it is the right thing to do???
I stand and say, yes they are based on something indeed. They are based on God and His Word and his nature. The very nature of God is opposed to wrong doing and from the down of time this has been written on the hearts of mankind; Even mankind who knew zero about God or that one even existed.
Culturally, civilizations have generally had some form of law and order based on certain absolute truths inherently known by man....without knowledge of God or a Bible to read. How is this even possible for the world over in ancient times to inherently know that murder, theft and other actions were wrong? It is possible because God wrote it on the hearts of all mankind. Now some may choose to ignore that internal call and wander off into evil, but the calling is still there.
The Bible supports this supported as well:
Romans 2: 12-16
2 For all who have sinned without the law will also perish without the law, and all who have sinned under the law will be judged by the law. 13 For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified.
14 For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. 15 They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them 16 on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
The Old Testament for Jews and for Christians writes them down, but they were already in our hearts outside of the Law.
So our system of current laws on murder, theft, rape, etc... are based on God and Biblical Truth. They are in fact religious in nature, not just in the USA but globally it exists too. There have been subsequent and numerous perversions of God's natural moral law and truths to be honest. But that doesn't erase the facts demonstrated by god's Word and in the cultures of people without God.
Marriage and family is the heart of civilization and culture. Homosexual re-branding of marriage and family is a systematic attempt to unravel and change the heart of the culture by the Progressive Movement. Why? The goal is to separate men, women and children from God. Destruction of marriage by redefinition is just one way of accomplishing that. Heterosexual marriage is having issues as we all know.
If men want to have sex with men, women with women...so be it. It has always been an issue and always will be due to sin. But changing the definition on marriage within a country that was founded upon Biblical principles and precepts and ideas...well it's just wrong in my opinion and should not be allowed.
But to say that religious morality should not be applied is to ignore the other applications already existing.

This goes to worldview again. A Biblical worldview that is true and accurate gets it.
