As a common sense Catholic, a "conspiracy theory" isn't outrageous or ridiculous at all.
conspiracy = 2 or more men getting together to create and carry out a plan, usually in secret
theory = using one's brain to try to figure out something, based on indirect evidence and logic, since none of us have video camera feeds running 24/7 in every room in America.
Why is it so ridiculous to believe 2 or more men would try to create plan(s) and then try to carry them out -- without shouting their plans to the world?
I don't find that unbelievable at all.
Especially as a Catholic, we know for a fact that the Jews have been in a 2,000 year battle against Christ and His Church.
