What Dobson doesn’t understand is that what he wore was irrelevant to his job and thus had no affect on his professionalism to his peers and superiors. The sciences are probably one of the more lenient areas when it comes to dress codes in genera.
You can wear t-shirts, shorts, sandals, have piercings and tattoos, the facial hair or hair style you want, etc so long as your outfit doesn’t interfere with your work, that you wear proper clothes when required (No wearing t-shirts and cargo shorts when handling ebola), and that you cover up a socially acceptable amount of skin.
Because in the sciences, what you look like isn’t what’s important. It’s what you do and the results you get. Perform your experiments, analyze your data, and publish your papers. This applies to men and women of all creeds and colors because that’s what the sciences demand.
The guy he’s talking about, Matt Taylor who helped land a probe on a comet recently in the RosettaMission, got a lot of flack because the shirt he wore had underclothed women. Not naked mind you, just showing a lot of skin.
His shirt was gifted from a friend: 
He likely wore it because it held sentimental value. After all, a lot of people would be watching the livestream so he probably felt as if he was doing her a silent favor by exposing her work to the masses. Some innocent advertising if you will.
But SJWs like Dobson care not for context or intent. They claim that this kind of thing drives women away from science but I’ve yet to see any names from actual scientists upset over this. Everyone railing on him are communications and gender studies majors. One of them was part of the infamous GameJournalPros list which ties this crap back to GamerGate.
And where is Dobson coming off like this from? The man’s a cartoonist who doesn’t draw. He’s an artist who fails at the fundamentals of art. He regularly rails against his superiors, make long whiny bitch journals/Twitter posts under his real name (ADobsonComics). He blocks criticism and dissent.
What gives him the right to tell someone who actually did their job and did it well that they’re being unprofessional? The European Space Agency didn’t hire Taylor because they wanted a man with a good fashion sense. They hired him along with the other men and women involved because they need the engineers capable of building the prob. The mathematicians and physicists capable of calculating the probe’s trajectory by the centimeter and being able to navigate through all the orbits the damn machine has to pass through. The astronomers and chemists to analyze the materials that make up the comet. THAT was their job and goddamnit they’ve done is well and are continuing to do so.
Matt Taylor wearing that stupid shirt was no less professional than Bobak Ferdowsi sporting a mowhawk during the landing of the Curiosity Rover.
