No. I am not missing the point.

Like you, I happen to believe that the baptised are called to be Christ in the world of today.

It is you who have has missed the point. This is a point of theological belief.

Alongside that belief there is the existential reality of Christians living in the world ... and how they do that (or fail to do it) is legitimate material for discussion by the world.

If, trying to explain a theological point you made a spelling mistake, people would be justified in pointing out "you made a spelling mistake". Saying "But I was making a theological point" would not be a valid excuse.

So, too, social sciences are perfectly entitled to point out what they observe about the "culture" of those who call themselves "Catholic". Saying your theological ideas are "huge" misses the point.
