Dude,
I don't know if you had thoughts over Shabbat & reconsidered...
In any case, Shavua Tov... life is long & we learn & get greater.
Truth is that lots of dudes who claim to be Talmidei Chachamim, learn Rambam & know the whole Shas... are really fakes, pretenders & charlatains who know nothing because they don't understand basics of Torah Judaism & Jewish Idea.
They are like some reformed who have PhDs in Judaism.
They study, quote & argue Rambam & Rashi & Ram & Gra & the Whole Gemorah with saliva fountain yet they don't understand a word that these taught.
On the subject of taking charity from Goyim....
Many Jewish lives could of been saved from sand-nazi terrorism in Israel if donations from sincere Christians & other "horrible goyim" would be graciously accepted, used properly to enhance security that is lacking, medical aid, guard dogs, equipment, training, etc.
Donno about my honorable opponents, but since I lost a dozen friends & neighbours to arab bullets, knives & explosives since 2000... after every funeral I had thoughts.
Since hords of big mouth & fat snout yids don't give a [censored]... we should accept money from "horrible" goyim.
I'm pretty sure that if all the Great Rabbonim of the past, including Rambam, would see our dead who could be saved by better defenses, even paid for by goyim, they would agree with me.
But there are lots of paid shabak snitches, leftist pigs & arab terrorist advocates in addition to stupid naiive yids who think they defend "mitzvos" by taking blood on their souls & discarding basic ethics, moral guidance & common sense.
I am very sorry, but I don't see how quoting misunderstood Chazal helps that.
