I don't for the most part. While I believe the WTS and JWs are no better than any other religion (worse actually), people have the freedom of religion. If one is happy in that religion then it's none of my business. If they are not happy and let me know they are in doubt, I'll help them somehow. If they challenge me and my position, I will defend myself. But as an inactive person who hasn't been in a KH for over a year, who doesn't go to assemblies, who hasn't been in service for 5 years, they rarely have a chance to speak to me let alone challenge me. The sheparding elders seem to have given up. They can't answer my questions. So they don't get themselves into a position where they are stumped.
The downside to my position is that even though I don't begrudge JWs their religion, I know that they begrudge me not being an active member of the congregation anymore. It really is a double standard. But I'm not going to stoop to their level and hate them or speak ill of them (as individual members) as long as they leave me alone.
