As far as I’m concerned, Religions are categorized first by who their god is so I’d lump these and more together.
Abrahamic Religions: The most prominent Abrahamic religions are Judaism, Christianity, and Islam.[3] They—alongside Samaritanism,[4] the Druze faith,[5] the Baháʼí Faith,[3] and the Rastafari movement[3]—all share a common belief in the God of Abraham. Likewise, the Abrahamic religions share similar features distinguishing them from other categories of religions:[6]
And to many people the differences between Judaism, Christianity, and Islam are negligible.
Sure, it’s a matter of what particular aspects of religion you care about, and Judaism and Islam aren’t monoliths, either.
Then they don’t understand them at all.
There are very foundational differences between them.
I say this as an irreligjous person who’s studied world religions.
They only appear similar when viewed through a very low resolution/highly abstracted perspective.
