Get this hypothetical scenario:
You go to your JW friend's or family's for dinner. They break out the candles and light them. You jump up, hold up crossed index fingers and back away, or two upright index fingers (torture stake, of course) and back away, with this look on your face. You make a bee line for your car. They chase you down. "Was it something I said? Are you allergic to beef??"
"Noooo. You lit candles. They do that in churches you know. I'm getting the sheol out of here and reporting you to the elders, unless of course you can run to your phone and beat me to it, with a confession that is."
If an individual chooses to burn incense, his decision should take into consideration both his own conscience and the feelings of others.
I mean, if we based all of our life's decisions on the feelings of others, we'd NEVER follow our own consciences. Duh. Or live for that matter.
