"being that" なんて知らなかったけど、それは nonstandard だと
次の解説文の中で書いてあるね。

being that
★Using “being that” to mean “because” is nonstandard,★ as in
“Being that the bank robber was fairly experienced, it was
surprising that he showed the teller his ID card when she asked for it.”
“Being as how” is even worse. If “because” or “since” are too simple
for your taste, you could use “given that” or “in that” instead.
