All Catholics cannot be put in one category to be bashed.
Likewise, all Protestants cannot be put in one category to be bashed.
You might say “your belief in ****” is misguided” and you’ve violated the rules. However if you say “Catholics/Protestants belief of ****” is acceptable even if it’s not accurate.
“Unfortunately if you respond to something from a specific person you are making it personal. Both sides are limited to broad statements.”
That’s untrue on two counts:
1) Almost always only one side is said to be “making it personal”.
2) There is at least one example of a “broad statement” somehow, inexplicably, being turned into a “making it personal” situation.
