We really don’t need Catholics here to talk about Catholic teachings and doctrines. It’s all documented and it can easily be referenced, without involving any individual Catholic who may personally be offended because the Catholic teachings and doctrines are defective and in error.
In fact, they get in the way when they start to make it personal. It really has nothing to do with them personally, as Catholicism is a defective and errant system!
SO ... if individual Catholics feel offended, all they need to do is leave, because we can easily talk among ourselves and they won’t have to listen ... :-) ...
On the other hand, if they stay, then stop feeling offended and accept the fact that others think that they are following a defective and man-made system that is full of doctrinal errors. They can attempt to defend it, if they want ... but stop all the “wah, wah, wah” stuff and whining about it ... :-) ...
