Amazing how non-Catholics tell Catholics how they must worship. It is the same as the way Leftists try and tell me how to run my life.
I grew up Catholic but am considering the Baptists.
That said, I don’t think it is my business to tell Catholics how to worship. It is between them and God.
One can say politely and with a real difference of religious dogma that kissing the feet of a statue is not true to the precepts of Protestant Christianity which is more bible-centric than the Catholic church is (in my experience) but that “polite telling” is not what I see here.
Just my opinion.
