I cannot speak to the interview because I didn’t hear it, but in regards to some Catholics over emphasizing Mary, I think that is true. I, too, have experienced people advising others to pray to Mary, the Saints–but not to Jesus or our Father! I’m not sure what is behind this, really, but it is not the Church’s teaching, as you have intimated. The Church teaches that we worship ONLY God–Father, Son and Holy Spirit. This is termed latria. Mary is given highest veneration of all human beings because of her unique cooperation in the salvation of mankind. This is termed hyper-dulia. The Saints triumphant (those in heaven) receive veneration, too, because they held fast to the faith to the end and have been made perfect. This is called dulia.
I am speculating here, but I’ll venture a few ideas: First, I do suspect that some Catholics are a little blurry on what the Church teaches in respect to this. Perhaps some do not understand there should be a definite distinction between worship of God and veneration given to Mary and the Saints. Or perhaps it is the uncomfortable feeling that comes over some who feel that God is so transcendent that He is, therefore, completely unknowable and unreachable (and admittedly, we are limited in knowing Him wholly). But coupled with this, they may not really comprehend (at least viscerally) that He is personal, immanent, and desires a love relationship with them. Finally, part of it, today, could be a knee jerk reaction to Protestants’ underemphasis on Mary’s role in salvation. Whatever the case, I feel your pain! I do not think people are consciously focusing in a wrong way. I think it is a blind spot, done for reasons we may not be able to relate to or comprehend. I think it is something to pray about
