Of course people’s views are “evolving”. They are bombarded 24/7 wth the gay agenda. Every TV show features a heroic and/or funny gay couple. We are told constantly that gay is good and anything but full acceptance is “homophobic”.
On the other hand, most of our churches avoid the issue and some openly embrace gays to the point of ordaining them. Even if the churches would condemn it as a sin, most people spend 1 hour or less each week in a church so there’s not a lot of time for influening people’s minds.
This is how a vocal, well organized minority can move nations. This is how communists came to rule Russia and how homosexuality and drugs are now acceptable. You can’t play defense all the time. Always being against things. The most successful conservatives didn’t go around talking about what people shouldn’t do, but what they should. Much easier selling a point of view when you’re actually for something. Even if that is traditional values.
