It seems to me to be hypocrisy to attack Catholics without revealing one's own affiliation. Would you agree ?
No, because it's not comparing doctrinal differences between Catholicism and another denominations.
It's comparing the teachings and doctrines of the Catholic church to SCRIPTURE. Since SCRIPTURE is without doctrinal affiliation, there is no need to associate any particular church with it.
Catholicism can be shown to be wrong about a number of things simply by comparing it to a ordinary, clear reading of Scripture. The only ones who can't see that are the ones who have been indoctrinated by their church and have had it *interpreted* for them.
Additionally, Catholics do have their own personal interpretation of Scripture. Their accepting the Catholic churches interpretation is still a personal decision based on heir interpretation that the Catholic church is correct. They just let someone else do the thinking for them and go for the group hug kind of mentality.
BTW, If you think that anybody can't see through that lame attempt through manipulation to find out church affiliation, you've got another thing coming. People know when they're being baited. Using twelve year old tactics to try to coerce information does not speak well of anyone.
