It's great that you were able to answer your own question.
If the answer is no, then if it makes someone uncomfortable you have to drop it.
This is not the same as every kind of thing that can make someone uncomfortable. Should people reasonably expect to have their performance reviewed at work? Yes. So if it makes them uncomfortable, too bad...
In regard to verbal sexual conduct I would say it is certainly undesirable in a work environment. I wouldn't allow it for a second if I ran a company, but this isn't my company. If Upload want's sexual conduct to be a part of their work environment, it's a dumb choice, but it's their choice.
You can't brow beat society into being perfect, you can only give people basic rights and hope for the best.
I'm sorry but I just don't think anyone has the right to be free from verbal harassment. I challenge you to even come up with a definition for verbal harassment that could be universally applicable.
Is it the verbal nature of it, that leads you to believe people have no right to be free of it?
As a counter example, consider that verbal intimidation is just as illegal as any other kind.
For example, if someone has questions about the quality of their work, a person might feel threatened — they might be afraid of getting fired — or they might be offended — they might be proud of their work. But we accept reviewing other people’s work as part of the work place, whether or not it offends or threatens.
Emotional response is not enough to establish that something (a) is illegal or (b) should be. With regards to feeling threatened, for example, we have to ask: Was the threat of something unlawful? Being fired for doing bad work is not unlawful; being fired for not putting out is.
