The applicant has every responsibility to maintain a degree of professionalism.

If they entered into a conversation with overtly 'cheeky' and sexual context, then they've set the tone themselves.

More importantly - the victim here could be interpreted as the instigator of sexual harassment.

Imagine a man, wearing a T-Shirt at the office, that said 'When Was The Last Time You Were PENETRATED?' - he would be taken aside and accused of sexual assault or unwarranted behaviour, right on the spot, no conversation needed.

The word professionally or professionalism are weasel words that don't hold up to scrutiny. Competence is necessary by every definition I found, so how, exactly, are you going to determine competence? By my measure everyone in management at Blizzard should be immediately terminated for lacking professionalism.

That presumes everyone agrees to the same standard of professionalism, which isn't true, not even slightly.

> If they entered into a conversation with overtly 'cheeky' and sexual context, then they've set the tone themselves.

Why are you blaming the victim?

If reading words on a shirt instigates someone else to behave like that, then they should have their mental state evaluated.

I've done exactly what you're describing several times at a few different organizations of various sizes. I think you're going to be very surprised how Twitter and corporate media aren't a proxy for real life.
