“Don’t you mean a Chillul Allah?”
No I mean if they find out that a kosher store was deliberately misleading them it could be bad. Though admittedly, I am grasping tryingto figure out what could possible be the OP’s concern
“while the more balabatish Muslims are OK with eating the regular, kosher meat”
Exactly right and the frei ones dont even care about that. There are over a billion of them. They dont all practice the same thus this statment “Anything that’s Kosher is Hallal ” i true accroding to many though not all muslims.
Although even my coworker (not “friend”) will eat kosher if there is no halal available
