Since this is a double-edged sword, it doesn't matter if I post this publicly.
I got an idea from dealing with 3 feisty Watchtower (WT) apologist debators.
These WT apologetics have gone out of their way to defend their master, while WT keeps control of JW slaves and the Bible hostage. You will find them in various websites. They are really cyber preaching for WT.
Seek them out and neutralize their luring and hooking cult mind control efforts. You might be able to win them over if you focus on the real problem - Watchtower.
Also why not immunize your friends and family from these advancing proselytizers. Be calm and calculative. Keep your witnessing and testimonies appropriate to the audience to prevent back-firing. Be mindful of the "locals", since this is a "surgical strike" to help neutralize WT efforts you are not there to have any fight with the locals. Avoid the locals if they pick on you.
