I have witnessed these actions with my own eyes and can assure you that non-Catholics have done this on a regular basis. And seeing as you don't know the protestants I know, and I have not seen the things I have seen. You can not say otherwise. (Sound familiar)
You may or may not have witnessed what you claim. We cannot confirm or deny your statement. However, let's presume your statement is correct.
The practice you cite is not accepted in Christian circles as it is condemned in the New Testamemt as is the catholic worship of Mary which is practiced widely and endorsed by catholicism.
In all the years of being a Christian I have never witnessed the practices associated with your assertion of Bible worship.
