I don't really see what you mean about bringing the profession into disrepute? It's not like they were on TV badly inserting IV lines.
I also don't get why we're so obsessed with maintaining a weird 'professional' gloss over our entire lives. Every single person you've ever worked with has genitals. They also might be into weird sex stuff, be a Disney obsessive, like to get smashed off tequila, lose their shit occasionally, just generally be an actual person. I find it so odd that it's unprofessional to in any way be a human with quirks and flaws - is professionalism defined by being fully dressed? By not being an exhibitionist? What exactly is it that is unprofessional about going on a TV dating show where you get naked?
Nobody goes home and gets into bed wearing their sensible Karen Millen skirt, having said 'kind regards' as they tucked their children into bed, and then watches 1 sensible hour of Workplace Safety and Etiquette videos before they sleep. People are people.
(Disclaimer: I work somewhere where we don't wear 'professional' clothing, we all have lives and personalities and hobbies that we often discuss, some of which would I'm sure be deemed unprofessional by corporate drones, and we are all successful, hardworking and no less efficient for not pretending we dream about Excel spreadsheets)
