I've always tried showing the people in my life of religious persuasion that atheism or secular humanism are not what the religious leaders and politicians attempt to paint them as.
I don't feel the need to advocate outright, push my beliefs, or bash others beliefs because we are going in the right direction, and religion only gets older and more porous. Fight for the free transfer of information and religion will have fewer and fewer shadows to hide in.
But I’m an imperfect being and YECs make it so hard to resist. “Dino fossil ages are fake to sow doubt so that we can have free will,” is just so hard to not make fun of.
