Those personifications aren't meant to be taken literally. The poster you're replying to isn't saying that there aren't such personifications, rather they're saying don't confuse the symbol with what the symbol points to. And additionally they're saying that most Christians understand that the symbolic image of the Heavenly Father is not the actual, theological Heavenly Father.

The Heavenly Father is a symbol that represents the very metaphysical structure of reality, that is "God" as "He" is so-called.

I've read the Bible front to back and have spent hours upon hours contemplating Christian theology. I am certain the poster you are replying to has probably read the Bible and, in fact, understood it far better than yourself or any of your imagined Christians did.

If someone calls you a Lion that doesn't mean they concretely or literally think you're a big African cat. So on and so forth.
