It comes off as strange to me because it doesn’t make a difference if a “sex worker” is intelligent or not. And this goes for any job that doesn’t require brilliance. Am I supposed to feel better for, more accepting of, more sympathetic to, etc. a person because of their intellect? And if I have a problem with sex work, it has nothing to do with how I perceive the intellect of the workers, so the pre-empting seems unnecessary.
Maybe comments should read each others’ future, unwritten comments in the most charitable light possible. Otherwise it starts looking like we’re writing up preemptive strawmen.
Also, it is quite clear that comment was written to elicit sympathy. I can see why someone gets angry when intellect is used as a justification for sympathy.
