Reply To: Milchig Meal on Shavuos

“while sefardim are machmir on not mixing fish and milchigs many ashkenazim are not ” – yes, askenazim who don’t know better, are meikil (even those that pride themselves with being machmir in halacha and are mekabel chumros of various shitos). There is some leeway, if the sakana is “milk” davka with fish, vs. butter, cheese etc. So there is room to wimp out and be meikil. But if you accept the Chasam Sofer that milk is basically an animal by-product, then eating lox with cream cheese id the same as eating lox with roast beef.
