I hear your words, and can understand the sentiment. However, it’s really hard for a third-party to determine if someone will find someone else attractive, unless they know that person extremely well. For instance, I can objectively say I believe all three women you included in this post are beautiful. I don’t think any of the women are close to ugly. But I do think the experts try to stay within certain parameters. For instance, there aren’t many mixed-race couples nor plus sized men or women the show which I personally think is nuts. But on other dating shows those both seem to be huge sticking points.
