Typically this is a Christian argument used against Islam - but I’m actually curious if this is seen as a valid argument from a secular point of view? (Even if it’s not the “best”)
Because essentially it’s “your holy book contradicts the holy book it claims to be endorsed by”, which personally I think I can see working on a secular level, even if you don’t actually believe in the Bible either.

The problem is that you do hurt people by believing in untrue and harmful ideologies such as Christianity and Islam, both of which harm people, especially children.
