See rashi on yaft elokim leyefes; even a positive admixture causes the shechina to depart
The maskilim try to have their cake and eat it too, by saying that they should be allowed to mix with goyim and change the mesorah…. And that they’re “really* the traditionalists, because only the chasam sofer started a new mahalach that you can’t change. That’s a stirah minay ubay. If it were true, why would suddenly all the people who just happen to be meticulous in halacha get up and make up a new religious model? Fear of losing their “control”? If that were true, that’s accusing the gedolei yisroel of falsifying Torah, something the maharshal says is yehereg velo yaavor.
Chazal said torah bagoyim al taamin, and that includes all hashkofic issues, as they’re hilchos dayos. ואבדיל אתכם מן העמים להיות למ, i have separated you from the goyim to be mine.. Chazal say if you are separate, then you are mine.
