“I’m not sure what you mean when you say “Catholicism has Buddhists, spiritists, and cultists.” So do “Protestantism,” and “Judaism,” if you want to talk about people who are deviating from their own norms: the Baptist lady who believes in horoscopes, the Jewish guy who is also a Buddhist monk (Leonard Cohen!)”
In Asia it numbers into the millions and millions. And I believe it is deliberately tolerated for the numbers that can be counted on the rolls, and the coins that that keep the elaborate church buildings maintained.
We not only would but DO openly preach the falacy of it if we see it in our churches, and membership is not permitted without genuine repentance from idols (1 Thess. 1:9, 10; etc.), certainly not participation at the Lord’s table, because to permit such is a denial denial of the Faith of Christ.
We do not permit membership to any who maintain false gods or are members of false religions, or who are members of secret societies, or who take secret oaths in any organization.
I'm not sure what you're saying here. Are you saying there millions of Buddhists in Asia (Japan? Vietnam? Elsewhere?) who contribute to the maintenance of Catholic church buildings? I am not aware of any such, but perhaps you know more than I.
Please explain.

Who is "we"?
I have never seen a single idol-worshipper church; they are apparently rare in eastern Tennessee.
