I mean it looks like an office in their home, which is where such an error is completely understandable and forgiveable
Also, in the right context and to the right person a slightly-comically proportioned phalace can be a very funny and heartfelt gift especially when paired with a good punchline. I have a relative who works for the government, and received a penis-shaped bottle opener as a gift from a colleague in another agency after working a long-term project together with the attached commentary that his team wasn't the easiest to work with. Knowing the recipient plus how he loves to pull it out and tell the story every chance he gets, it's probably the best gift that he could've gotten.
Labeling that as unprofessional is kind of arbitrary, which was basically my point.
Although sex is something as natural, normal and common as eating, sleeping, shitting, having hair and whatever, some religious people a long time ago felt like this was something that needed to be tabooed, which I find stupid, because it has led and still leads to a lot of problems.
I'm glad that this started to change, but still, having some harmless sex toys on display shouldn't catch so much attention imo.
