I’m a little late to the party.

Whoops.
I think the issue most Protestants have with Mary is that they think that it is much more beneficial to go directly to Jesus and Mary is a distraction from that direct connection with Him.
This is, in fact, quite to the contrary! Mary is the most perfect road to Christ. If we are to imitate Jesus as perfectly as possible, then we need to spend every second of our lives devoted to her, just as he so perfectly demonstrated.
Someone brought up the point of spending 20 minutes with Jesus and 40 minutes with Mary might be a great detriment to their connection with Jesus. In fact, I spend all 60 minutes with Mary! This is because When we pray to Mary, we are not getting distracted from Christ, but rather are being
focused on Christ.
I think praying directly to God is a wonderful, wonderful thing to do, but just think of how perfect Mary can make your prayers if you pray to her. She will, being perfected in all virtues, most generously perfect and even embellish your prayers and then offer them to God. Who could know God better and what pleases Him the most more than his Holy Mother? Mary knows exactly how to give the most glory to God, and we don’t. Since we’re certain she won’t reject our requests (if they be in accordance with God’s will), why not ask her to make our prayers perfect?
Since Mary’s greatest wish is that we please God as much as possible, spending time with her will only allow us to more perfectly please her Son, Jesus.
If we imagine Jesus as the sun, then we can imagine Mary as the moon. The sun is so bright and so brilliant that we’ll be blinded if we look at it too long. But the moon only reflects that light, and so it is much more comfortable to look at. In the same way, Mary reflects God’s light, and so I am much more comfortable speaking to her. How unworthy we are to approach God! But when we approach Mary, we know we are only approaching a human being, just as we ourselves are. She can talk to God on our behalf.
Although talking directly to God has absolutely no bad aspects to it, speaking to Him through Mary shows Him your humility in recognizing your unworthiness to speak straight to Him.
Being the spouse of the Holy Spirit, Mary was given all the graces possible (“Hail, full of grace”). God has given her the power to dispense these graces to whomever she wills and in whatever amount she wills.
So, let’s not be afraid of being “too devoted” to Mary. It’s practically impossible to overdo it (short of worshipping her, of course).
Lastly, I thought it would be pertinent to explain the levels of honor we give to the saints, Mary, and God.
Latria - Worship; given to God alone
Hyperdulia - “Hyper-praise”, given to Mary
Dulia- Praise, given to the saints (or anyone you like, really)
“If they will permit her to do so, she will mould them into perfect images of her Son. Let a man melt the self-love in him and throw it onto the desert sands; then let him pour the molten gold of his love into the heavenly mould of the Mother of God. The gold will be shaped into perfection.” -
