The nation that we've grown up in has changed. It used to be that people treated each other with respect, even if they disagreed. A Christian could believe, and teach that abortion and homosexuality are a sin, and people let them alone. A Christian could believe that God created the world in six days, and those beliefs were a least tolerated.
But today, if you express those beliefs or most any Biblical standard, you are scoffed at, impugned, and hated. You are a candidate for a reeducation camp. You are called a racist, bigot, sexist, homophobe.
So, to Christians, first; Welcome to the rest of the world! And second, "How do we live in this new world?"
