I do not think it is fair to say/suggest the Witnesses are a 'more deadly cult' than Jonestown or the Branch Davidians. I know it seems clear that more JWs have died due to the blood transfusion rule than in those other groups, but the percentages are much lower. This kind of statement sounds to me like when the Society says 'More people have died in earthquakes in the 20th century than any before it' which always ignores the significantly higher population levels today.
I wish I had not been raised a JW and I am very pleased I never needed a blood transfusion, but given the choice of doing it all over again or growing up a member of Jonestown I think it is obvious which group we would all choose, and saying JWs are more deadly and thus suggesting that the Governing Body's rules are more life threatening to their group's members than Jim Jones must make us appear ridiculous to secular media.
I am a member of AAWA's facebook group btw, and have made quite a few facebook 'friends' through the group so I am not anti-AAWA, just sharing my opinion on this one subject.
