TheWiz,
As a Catholic I will admit that the Church has a poor track record of dealing with abuse cases, but percentage wise the WTBTS is worse by far.
Also, an interesting fact, by percentage pediatricians are more likely to be pedophiles than are ministers, according to a 1999 APA article.
To some of your specific charges...
The Tablet is a news magazine, and fairly balanced. The WT & A print drivel, misquote, make up quotes, etc.
The Church was responsible for saving 800,000 Jews, and was hailed as the loudest voice in europe against Nazism. More Catholic Priests were killed in the camps than there were JW's IN the camps. Over 3300 Priests were killed in Dachau main camp alone.
The Inquisition, a bad deal no doubt, but people have exagerated it. In the Spanish Inquisition torture was used in only 15% of the cases and death in less than 2% for a total of only some 2400 dying. The Spanish Inquisition, as bad as it was and the church should have had no part in it, was the most liberal court of it's day.
For all it's faults the Catholic Church has helped far more people than the WTBTS could ever hope to.
As to the doctrinal issues you mention, the Trinity, etc, I'd love to engage you in a debate, care too?
