In general, one would do well to restrict oneself to "pontificating" on topics of which one has at least a passing familiarity.
Your assertion regarding Catholics is both false and ridiculous, and reflects very badly on you and whatever religious confession you claim.
May The Lord enlighten you with The Truth.
I do think that some know that Mary is indeed prayed to and worshipped within the catholic belief system, even though she is dead and unlike Christ she was not raised from the dead. ......But not all SEE their worship as that....the same with praying to dead Saints, and the carved idols throughout their church buildings. They see it as something else...more like another draw or means to accessing Christ...a help so to speak.
Yes, this does fly in the face of the sufficiency of Christ but some appear to need these extra helps. I do know that many of those who find themselves involved in cults often say that they needed more than what the Christian church offers....they needed “experiences” and ‘supernatural happenings’, signs and wonders apart from the Gospel message itself. They need more and evidences of Christ beyond that which is given. Thus many who leave cults do end up in catholic churches because it offers them the extra they believe they need.
