I don’t remember what I learned. I think it’s technically less of an issur than eating treif, but it could be that given the choice it’s better to eat treif even though it’s technically a bigger issur. Kind of like how it’s worse for a man to marry to goy than it is to marry a Jew who doesn’t keep taharas hamishpacha even though the second one is technically a bigger aveira.
But I don’t remember and I might be wrong (about both issues). I’m sure some of the men here have learned it. Ask them.
