"[If] anyone in his workplace was bothered by his shirt, they should have talked to his manager, and those actually affected could have resolved the issue like adults."

You're implying that only people within ESA could have been affected by his choice of clothing. But he wore that shirt in public; worse, on broadcast media, which means that those potentially affected includes the media-consuming population of the whole world. And anyone who is concerned about access to and diversity in science and technology has a right to be "bothered" by the message it sent out.

"those potentially affected includes the media-consuming population of the whole world"

I really don't know what to say. Here we have people insisting one moment that I'm blowing this way out of proportion, and then the very next moment insisting that billions of people were harmed because an obscure space scientist wore a shirt.
