Since the literal interpretation of Genesis is alien to both liberal and traditionalist Catholics, apparently it's all of them.
Have you ever been to those Catholic forums where even pre-VII traditionalists respond to any doubter of evolution by inquiring something on the order of which trailer park he resides in?
Actually I have been on a number of Traditionalist forums and have never seen this. That doesn’t mean it doesn’t happen but more often than not I see Trads that believe in the literal Creation.
I’m going to guess that the “trads” you’re encountering are those who are “smells and bells” trads who really are VII Catholics who “prefer” the Latin Mass. And that’s about the extent of tradism.
