Are Protestants underestimating Mary?

Ben Merritt of Cleave to Antiquity recently produced a video in which he interviewed an eyewitness of the Zeitoun Marian apparitions and concluded that he accepts the apparitions as appearances of Mary. In the comments section, Sean Luke of Anglican Aesthetics said that he holds a similar view. Other commenters also said that they're Protestant and accept the apparitions as appearances of Mary. In another recent video, Myles Christian of Canon & Creed provided "a historical survey of giants in Protestant history who held Mary in high esteem". He cites their belief in concepts like Mary's perpetual virginity, her becoming sinless after conception, and her assumption. Elsewhere in the video, he refers to a problem with Protestants "overcorrecting" errors about Mary. He asks at another point, "Are we possibly missing something that they [earlier Protestants] saw from scripture?" One portion of the video refers to an argument for Mary's assumption based on fetal microchimerism, but doesn't explain how it allegedly leads to the conclusion that Mary was assumed. He ends the video by commenting, "But if men like the reformers, who were radically committed to sola scriptura, sola fide, and the purity of the gospel, if they could hold Mary in high esteem without compromising their convictions, then maybe we can too."
