Dude, it's more than in spirit you catholics pray and worship Mary.
If someone wants to know what you believe, they should ask you, right? Not someone else. It's just common sense, and respect. You don't want someone else telling me what you believe. You want to say it yourself, in your own words, and to be able to clarify what you're saying if there's any misunderstanding.
So if you want to know what the Catholic Church believes, ask the Catholic Church. Not someone else. It's easy enough. The Vatican's website is available to all. If you do, and you take the time to understand, rather than hear what we say in terms of what someone else told you we believe, you'll come to understand that we do NOT worship Mary.
