My point is that, if you don’t personally know a person, your opinion about her has to be superficial.
Perhaps....I find her conservatism, realism, intelligence, quick wit, take no crap from anyone attitude quite sexy.
She’s also a great cook from what I’ve read.
So I gather what you’re actually saying is that any attraction one might experience concerning the opposite sex whether it be for physical or mental appeal if you don’t have a personal relationship with them is superficial.
OK.
“My point is that, if you don’t personally know a person, your opinion about her has to be superficial.”
But, if you take your point through to it’s obvious inference one would have to reason that your opinion of say Donald Trump is “superficial” as you do not have a personal relationship with him. (assuming you don’t)
