When the topic shows up I let anyone know that my parents brought me up in the JW faith, but due to some disagreements with that faith I find myself in noman's land when it came to religion.
Then, of course, there are the little digs other religious people try to give me since assume I may believe in stuff just like the Witnesses do. To that I've just responded that they'll have to inquire from a JW that is actually practicing their faith.
Some co-worker tried to put me on the spot and asked me in front of all the others about why is it JWs do this or don't celebrate that. I just calmly told her that if she really needed to know, write down these inquiries and the next time she called on her door don't be so quick to dismiss them; to make sure they don't leave until they've given her all the answers. Other times I've just sarcastically said that I discuss religion and politics only in private settings and if they would be interested in a house visit I'll gladly send a faithful JW their way; of course, they turn it down really quick.
