What I see is this:
1. Statues of Mary in churches that look a lot like statues of Jesus, and are similarly placed.
2. People bowing down to those statues of Mary, lighting candles before her, etc.
3. People praying to Mary, praising her, clearly in devotion.
4. Prayers to Mary as a prominent part of the rosary, used as a primary form of worship by some Catholics.
I also see some Catholic sources referring to Mary as Mary: Co-Redemptrix, Mediatrix and Advocate.
You can also find these titles on the Vatican website. For instance, here:
When people say, "this is veneration, not worship", I ask how I can see that difference. How do we respect human beings? How do we worship God? What actions distinguish one from the other?Thus there is a mediation: Mary places herself between her Son and mankind in the reality of their wants, needs and sufferings. She puts herself "in the middle," that is to say she acts as a mediatrix not as an outsider, but in her position as mother. She knows that as such she can point out to her Son the needs of mankind, and in fact, she "has the right" to do so. Her mediation is thus in the nature of intercession: Mary "intercedes" for mankind.
