Do you think having a prenup is an insult to your partner?

I personally wish to have a prenup agreement for one particular property only, not for all assets I own. It’s a business which has been inherited to me and my grandparents and parents gave their all to achieve. I’m sure they will want it to be protected as well. However guys never seem to understand this and they get all worked up and angry. It has nothing to do with me not trusting them, but they all say it’s an insult. I personally would understand in a situation like that. How would you feel?
