Are we talking about her natural physical appearance, or the way she has chosen to present herself? If a woman dyes her hair blond to look more like a bimbo in order to get a job on Fox News or as press secretary, is it OK to comment on that? Sometimes I'd like to see Elissa Slotkin make more of an effort to look less homely. She wore some makeup last night, but she usually doesn't or only goes with something very light. That's a choice on her part. She is communicating something with that choice. Note that I don't care at all personally, and I respect or even applaud her choice. It's just that I think it affects her electability, which is bad if she's the one to hold down a key Senate seat in a swing state.
I confess to being lookist for two people. When I see Sarah Sanders, I see someone who looks like a pig. It's not noble, but it's always my impression. Second, when I see Lauren Boebert, I see a woman who likes to suck dicks. Everything about her face screams, to me, "I give blowjobs willingly and often." That's even less noble, to the point of being downright dishonorable, but it's my genuine reaction. I would never let it influence my opinion of her -- or so I say, but I have no opportunity to test the thesis because my opinion of her is already much lower than that.
