If asked about my beliefs I tell them I am an Atheist....If somebody comes to bug me talking about religion I, also, tell him/her I am an Atheist....but I don't go out of my way to talk about the subject because there are many ignorant people roaming the streets of this world....and I don't have time for ignorance.
I like the idea of setting a time and place to discuss the sensitive subjects. I enjoy politics, economics and philosophy and many others do not. For the few of us who share similar interests, we can squirrel away with chips, nuts, pretzels and beverages and have a good old gabfest. We have a rule of no violence, physical or emotional. Other than that, we chatter like chipmonks.
I look forward to reading about your experiment. It may catch on in your family.
Jerry, how did your reunion turn out? Did you have your hour for talk about politics and an hour about religion? I think that would be a very nice way to get the elephant off of the dining room table.
