I'm sure you understand they don't feel they're wasting their time anymore than you think you're not waisting yours.
Two different schools of thought; they feel they're teaching people how to fish, and you prefer to just hand out the fish to people. Both acts produce some good, so more power to you both in your 'good' deeds.
They shouldn't have called your actions 'stupid', though. I sure don't agree with that. By that expression, they sure didn't put into practice what the Bible teaches about refraining the tongue.
I've caught some JW relatives talking down to non-JW relatives about their charity work, and I have to remind the JWs that we must treat all with respect, even if we have more liberties with them as they're family.
