I paint with a broad brush since protestantism is as varied as its adherents and has no unified doctrine or practice. Anglicans will use the title "Saint" although it seems to carry not very much significance for them, a quaint tradition for naming streets and cathedrals. I was never one of them so it is hard to judge. The Via Media places a strong emphasis on avoiding those topics which divide the more Catholic-minded Anglicans from the more Protestant-minded ones, so it makes sense to me that real contemplation of the title's significance might be discouraged.
Mainland European Protestantism, as well as the Radical Reformation (which American Protestantism is somewhat strongly linked to), tends to have a strong aversion to the title. Lutheranism might vary a bit since it is not that radical in most places, but Reformed churches, Evangelicals, Baptists, etc. have a negative visceral reaction. Your average Protestant is offended at the idea of considering someone else holy, just as he is offended at the idea of considering someone else noble. (Democracy in state, in society, and in theology.)
Anyway, that Thai dancer should be unsurprising in any Roman Catholic church. Their custom is "enculturation," achieved by reimagining the Lord and his saints in the local populations which they conquer and (most often forcibly) convert. "Marian apparitions," the "Our Lady of [insert blank]" phenomenon, is endemic to Roman Catholicism. Guadalupe being the Mexican example most famous in the US. They waited for some woman or child to announce that the Blessed Virgin had appeared to her, along with the Child Christ, being of the local ethnicity. This image would then be widely distributed and proclaimed a miracle for the purpose of endearing themselves to the local populace. But in truth the practice predates their colonial expansions, given that already in the post-Schism Middle Ages the Roman Catholics had started painting Christ and his saints after the likeness of local human models rather than their known descriptions. It is how we got the image of Jesus as an Italian man in the first place.
Of course any rational person would look at it and conclude that it is a denial of the Incarnation, to claim that the Lord did not take actual human flesh from an actual human mother with a real appearance and a real ethnicity.
