Necessarily? OK. If we are going for that level of precision of language:
Islam harms society because its adherents will most likely do things or try and do things that cause harm, such as medically unnecessary infant circumcisions. I believe I have warrant for this belief because every Islamic society and the vast majority of individual Muslims practice or attempt to practice or express the desire to practice infant medically unnecessary infant circumcision.
Do you deny that there is highly likely an influential link between Islamic teaching and Islamic behaviour?
As for infant genital mutilation (as just one example of bad religious behaviour) being bad, I simply argue that it causes suffering for no reason. To show it has a reason you'd have to show that Islam was true. Good luck with that.
