Unrelated, but is astrology a "false belief"? There are some religions that take astrology quite seriously. I think saying that astrology is a false belief is similar to saying belief in Jesus is a "false belief". It's not quite the same as making an incorrect quantitative judgement about what the impacts of vaccination or greenhouse gas emissions are.
I didn't say it was "true". I said it's a belief system that allows some people to see a sense of order in the universe. I happen to not be one of them, but denigrating a religious belief isn't the same to me as pointing out a factual inaccuracy in a scientific argument.
The Catholic belief in transubstantiation -- that the bread and wine of the Eucharist literally becomes the body and blood of Jesus Christ -- is demonstrably false, unless you change the commonly accepted meanings of the words "body" and "blood." In any sense outside of theology and ritual it is a false statement. Doesn't change their belief. Doesn't even mean that you're denigrating Catholics if you're willing to accept faith as a virtue in its own right. Astrology makes potentially testable claims. Those claims have never stood up to examination. Therefore, outside of limited spiritual senses (which do not promise testable results), it is a false belief.
