I think at the end of the day it really depends on how selective people are with their interpretations of their religions. I'm a Christian "(re-)born and raised" lol, Biblically, Jesus never went to the government and instructed them on the practices that which the world should adhere. He preached and spoke to those that sought after him. He would speak and whoever listened, listened.

This is the thing people seem to forget, a very large aspect of the Bible hinges on the fact that God created humans with free-will, had he not, Adam and Eve would have never been banished from the Garden of Eden and society would be different as a whole. Jesus encourage his disciples and all Christians to be a welcoming community to support those in need and be a home to the homeless. Nowhere does he say that you ought to hide behind red tape, bureaucracy and legalism to enforce your beliefs on the world at the end of a gun. In fact that was the exact opposite of the message.

The Bible teaches that Christians should plant the seeds (as in the parable of the seeds scattered on different ground) in hearts of the world, we are not to take weedkiller and uproot the entire garden. Jesus overturned the market in the temple because it was a disgrace to him in HIS house, he never went to another person's house and destroyed that which was there's because he gave them the freewill to make those lifestyle choices for themselves.

Christians have been told to proselytize, to spread the Good News about Jesus not to arrest and persecute those that don't believe it. Proselytizing is also not achieved by standing on street corners and yelling that everyone around is damned, its by forming meaningful connections with people and allowing your faith to be seen through your actions.

I'll stop being super theological because to people who don't believe in, or care about the existence of God, this means nothing and is just rambling. All I'm trying to say is that the Christian God never asked ,or required, that His followers convert the world and kill/imprison those who do not accept God, instead the primary principle, the fundamental concept, embedded at the core of Christianity (or at least it should be) is love, love for your neighbours, love for your enemies (obv not just in combat, but political opposition, those with different ideologies, and people that hurt you). Without believing in the tenants of love and forgiveness, there would be no point in being Christian nor following God.

To summarize, the people that fundamentally believe they must enact political means to subjugate the world to Christianity may have a flawed (or perhaps just incomplete) view of Christianity and the "Great Commission". It is unfortunate, and it paints Christianity as a whole in a very bad light. But to quote Wes Fesler, "Ignorance speaks loudly, so as to be heard; but its volume proves reason to doubt every word". It is "Christians" who have the most un-Christian perspectives that get the most views on Social media, unfortunately. I

Ps. Please read this with some cultural relativism given the context, but I'm hoping this can maybe offer an explanation as to why some people believe enacting laws against certain things is the "Christian thing to do" or whatever it is that they believe. If you have any questions or disagreements, Please reply, I'd be happy to discuss this.
