I was clear form the onset that I make shlisel chalah as did my parents. That said I have little doubt it is an adopted goyish custom. This has all been discussed previously. I didn’t mean to confuse you.
Im not sure which part of your post I didnt reply too (I certainly didnt mean to ignore you)
If you meant this question “”If there is a problematic correlation, anyway, why didn’t previous rabbonim point it out and stop the practice?”
I did in fact reply, but will repost here:
a. They didnt know
b. The tzibur wouldnt accept it
