However, I've noted some radical methods that have been used by fellow exjws, and quite frankly, this must stop
Most of these radical methods are just to vent their anger on the JW's and not an attempt to reason with them.
Shouting at JW near carts, Protesting near KH's and Bethels, etc. may make an ex-JW feel good and may give him a way to vent his anger. But he needs to remember that instead of waking up a JW, he will have pushed ten more doubting JW's back deeper into the cult.
