That explanation would've been a lot more convincing if it was included before I called them out for using the Christian name.
"They used the Christian name because otherwise nobody would've understood" sounds a lot like a desperate attempt to cover for having a Christian show them up about knowing the basic terminology of Judaism while they complain about Christians "appropriating their culture".
A culture which by the way, Christians have just as much claim to. And Muslims as well. Turns out that all of the Abrahamic religions actually have a legitimate claim to these scriptures.
Which is why that potential whataboutism was only one sentence tacked onto the end of my comment, while the rest of my comment was a direct rebuttal.
Only focusing on the easiest points to argue against won't save you.
