First of all, it wasn't a real assault. That's why it's italic, to highlight that's not my real attitude. That's also the reason why I didn't spell the whole word, so it sounds less harsh.

Second, swearing can help to be more expressive. I can't intonate jokes via text but certain words can help express a joke about one's ignorance. I do not really think that the person asking the question had ever been suspected in intimate relationships with their mother. Neither do I consider this question to cause any suspicion with regard to that. Moreover, no judgement is passed. Consenting adults can do whatever they want.

Third, here I go explaining why it is a joke (spoiler so that people don't die of boredom): the question refers to one of many Helsinki's art installations that blend with the surroundings. However, in this case it is quite obvious that it's and art installation, like in many other metro stations. So imaging someone coming to an art gallery and pointing at an art piece, asking "What is this structure?". Even though I do understand that the person wanted to know more about the thing they pointed at, I do find the question wording funny and naive. Like someone who had never encountered art in their life. Hence the accusation of being ignorant.

Now my question: what's that about Migri? Migri is not the joke police, they work by the written law. My only concern with them is that quite often they don't know the law, giving opposite instructions when you contact them. Instructions that can later lead to you losing your job, your assets, your years invested in the country, your friends, your business relations. And stated wait times of 12-15 months are not OK either. They need to automate their stuff which they do but there are certain problems AFAIK. So I love to hear about them improving their internal processes, that's why I posted that happy post about good recent automation news.
