Do you use the English word G-d? Do you know where that comes from? I can definitely think of some non complimentary reference in Tanach.
We go through this every year. If people are following a Jewish custom, we are not Mechuyav to become historians and make sure it originated purely at home. We aren’t copying and following Chukas Hagoyim.
The way these references are tied in are do typical if these biased “research” articles. It’s actually quite easy. Find anything you want to attach, comb through the details, find a match, and bingo the connection is ‘crystal clear.’
