No, the problem is that Catholics won't listen to what Prots tell them sola means.
RC's keep fabricating what they wish it meant so they can shoot non-Catholics down with it, but strawmen are strawmen and while it may make RC's feel good, they are accomplishing nothing other than demonstrating to the world that they will not listen to others.
OK. I've listened, and I don't make the claim that "sola scriptura" means there can be no source of truth or information other than the Scriptures.
But my point remains (you skipped right over it) that the inconsistent use of "sola" by Protestants no doubt contributes to the "strawman" problem. In at least one instance (sola fide) it's used in an exclusive sense; then when the topic jumps to Scripture it's used in a different sense.
So, yeah, if you want your explanations to be clear, it would help to acknowledge this distinction. I'm not even sure most Protestants trying to explain S.S. are even cognizant of the inconsistency.
