Wow. That's exactly how I feel whenever one of those crackheads tries to push their satanistic paganism on me. Honestly, it'll take a miracle from the God they don't believe in for them to actually consider our angle from a logical, factual standpoint.
And, three people at one time?! Respects. I've only had to deal with two at a time at most so far.
If they simply won't listen, it may be a good idea to stop talking to snakes. But talk to God about it first.
I will be praying for you. Remember: God will bring all people to justice. And He will vindicate you.
