I do not see how putting your life in danger has anything to do with believing in Jesus Christ or whatever you believe in. The bible also says treat your body as a temple.
Yes I would tell them that putting themselves at risk from a serious venoumous snake bite is wrong, right to their face...why are they going to beat me up?. How would you feel about all the bad press if one of them gets bitten and dies? Maybe you wouldn't care but I can bet some of the other hot keepers who fight this press everyday would care.
I do not feel getting bitten by a deadly snake and dying is "standing up for my beliefs" And you are talking about them "smacking knots" what type of Christians are these who are willing to beat someone up because they don't agree? That is just childish. Fist fighting? Are you kidding me?
