"The bad examples are no excuse for doing nothing at all."
That's not what they do.

Disaster Relief
Since World War II, Jehovah’s Witnesses have organized relief efforts to help fellow members and others who suffer the effects of war, natural disasters, or other calamities. Our experience in organizing and managing large numbers of people at our Kingdom Hall building projects and annual conventions contributes to their success in this regard. Often we are the first relief agency to appear on the scene.
On May 2, 2008, Cyclone Nargis hit Myanmar with devastating force. Almost 140,000 people were reported dead or missing after a massive storm surge engulfed the Irrawaddy Delta region.
In one area of Yangon, Myanmar, Jehovah’s Witnesses helped many people find refuge in the Kingdom Halls during the cyclone. For example, at the Kingdom Hall in Dala, a Witness couple took in 20 distraught neighbors who had fled there for safety. In the morning, those families were hungry, but they had no homes to return to. The husband found someone selling rice and bought enough to feed all the people.
Initially, the cyclone left the branch office completely cut off because large trees had fallen and blocked the roads nearby. Just a few hours after the storm subsided, more than 30 members of the branch staff joined in clearing the trees by hand. As they worked, other local residents watched. Within a short time, a group of Witness women arrived with cold drinks and fresh fruit for the workers as well as for the neighbors, who could not believe what they were seeing. When a journalist observed the activity, he asked, “Who are these people who are working so efficiently?” After being told, he remarked, “I wish more people showed such true community spirit as Jehovah’s Witnesses do!”

There are opposers that will put the spin on anything Jehovah's Witnesses do. Identify yourself with a religious organization that can be subjected to criticism first, criticize second.
