Do you feel like there is a big hole in your relationship with your conservative friends? I felt like that. Anything even remotely gay related they didn't want to hear. It was like walking on eggshells. There was no way that you couldn't talk about such a big part of your life. There are very few safe subjects left so you talk about the weather or something equally trivial.
It's nearly impossible to change their minds because after all; God is on their side. Once in a while you will find someone open-minded enough to consider that they could be wrong. That would be the exception to the rule. You can try to keep a few friends from your closeted life. In the long run they will probably grow distant on their own.
"Beloved let us tolerate one another. For tolerance is of God and everyone that tolerates is born of God and knows God. He that tolerates not, knows not God for God is tolerance." 1 John 4:7,8
