Is it fair to say that someone's attitude towards body positivity and diversity should also be judged by who they sleep with?

There are many angles you can look at it from, and they're not always consistent in how we collectively respond - for example, we all agree that writing "No fats, femmes, and Asians" in your dating profile is vile, but we all have met someone who only sleeps with very skinny white twinks and it slides.
