Yes, freemindfade, I understand.
I usually say nothing, but when there are judgmental attitudes, I kick in, putting my "correction" in WT terminology that the most die-hard JW cannot refute (especially when an uber-JW spouts 'sinner so-and-so had his chance and I know Jehovah's mind on this!').
Also, I like to quote from publications on lame assertions that are based on the current mindless, ever-vacillating theology.
If you want to comment at all -- and that's a big WANT TO -- you have to use their bases of reference and understand where they are coming from. A left-handed version of theocratic warfare, I guess.
I do feel your pain!
