I am an atheist. I would not go to my local Catholic church and start an argument during their weekly bible meetings in the parish meeting hall.
If I met a Catholic at the local coffee shop, and the topic came up, we may have an intelligent discussion about our differences in a respectful manner.
One argument is disrespectful and out of place.
The other is a reasonable discussion between two people with different opinions.
It is called being an adult.
And nothing to do with this weak "P.C." argument people like yourself bandy about.
And I say this as a loud mouth, opinionated, emphatic dago from a blue-collar northeast family.
Meaning I rarely know when to shut up.
But I do know when and where (AND WHAT FORUM IF YOU CAN'T TAKE MY USUAL SUBTLE HINT) to speak, too.
Otherwise my louder, more vocal, and even more emphatic 5'0" tall mother would have and did, backhand her boys who did not have the good manners and the common sense to know when and where it was appropriate to speak up.
And my mother is many things. P.C. she ain't.
