Jws are are a reaction to Catholicism, that despite its shortcomings, stands for something far greater than they will ever even understand.
The only similarity is that they want to usurp the central role Catholicism, for historical reasons, always had in defining Christianity and what it means to be a Christian.
Catholicism was the cradle of Christianity, (its culture, its values, its heritage), and its guardian for centuries. Jws would like to reinvent Christianity in their own image, and substitute everything the Catholic Church has built for 2000 years for whatever it is (New World Order stuff), of which a lot of us in this site had already a taste.
