Daas Yochid- Thank you for your response. I did not have the plesi in front of me when I wrote my comment, I was relying on my notes. I will try to look at it again tomorrow, and get back to you. I would also add that it is possible to say that in today’s day and age where there fake meat and fake cheese is so prevalent and publicized in the media, perhaps there is no maaris ayin on these things. I would imagine that you cannot say that for milk from almonds or human milk but for veggie burgers or pepperoni pizza I don’t think it’s so shver.
Real Brisker- So you’re maskanah is the same as the maharsha’s havah aminah. I never said that what you’re saying makes no sense, I just said it’s wrong, and apparently you looked it up and can’t find an argument against that. “But I still doubt that one will find any rov eating a fake cheese burger.” C’mon, is that a tannah? The gemara clearly says it’s fine. Why you looking for problems? Honestly, I’ve never seen a rav eat any hamburger. And your chiluk between an udder and a cheese burger makes no sense based on the maharsha you yourself quoted. Think about it.
