No it doesn’t. A “chillul Hashem” isn’t determined by what the goyim think is foolish or unfair.
So is it a Kiddush or Chillul hashem if some “frum” jews decide according to the torah a 14 year old and 15 year should marry and there is such a mesorah for this.
And is it a “jewish Anti-Semite” who decides this is wrong and protests it.
