Sure, and maybe my manager is sidelining me because I remind them of their ex. Anything is possible. As I said in the original comment, an objection is a sign of a place you probably don't want to be working at anyway. I would definitely jump at the first sign of trouble, but I would wait for that sign. I wouldn't assume there is trouble without any evidence or avoid trying to negotiate on the assumption that it will cause trouble.
But hey, it's your career, you get to do as you like! If I was right about everything, I'd be a billionaire.
