If you wrote something someone thought was very privileged, and they said your post had "white cishet man vibes", would you think that they were possibly using clumsy language and did not intend the statement to be interpreted how it was written?

I think you sincerely believe it was a clumsy statement but I don't think you've given yourself the time to reflect* on how you came to use that phrasing on a website with a majority (I think?) of trans users.

*Obviously you can't "win" in this scenario where you want to give an apology quickly because you recognise it has caused harm.
