A few suggestions:
1. JWs say the holy spirit is a force not a power and maintain there’s a distinction.
2. It’s not just JWs who claim they aren’t Protestant, most Protestants would say they aren’t Protestants too.
3. JWs don’t have a “standard” view on sacrificial death and resurrection. They believe that Jesus was resurrected as a spirit being, not with a physical body. They also emphasise the Ransom as the mechanism for salvation rather than substitutionary atonement.
4. As I understand, it current JW teaching is that Jehovah is the judge and they can’t say for sure that others won’t survive Armageddon besides JWs. At various times it’s been suggested that uncontacted tribes in the Amazon and “people in China” might survive because they didn’t “get a witness”. With the very recent change in teaching the conception of who might survive is now possibly broader still.
5. Sparlock isn’t a recent cartoon. It’s about 15 years old now. People who remember it are probably adults by now.
It misses out some important stuff. Such as JWs refuse to fight in wars and have been the most imprisoned and persecuted religious group of the past century as a result.
