Sacred Haven of Debauchery

Therefore, the only way to determine its gender is to use its "gender" in the Russian language.

I believe that it is better to determine the gender of anything inanimate based on one's own preferences, because in the end, it is more about a metaphor than about any linguistic rules. And the assumed gender of the subject of conversation and the grammatical gender of the word used to refer to it do not have to match; this is acceptable in Russian. Examples include various job titles, which often lack feminine forms. Another example: when we see a "dog" in the street, we are more likely to simply call it a dog, rather than looking under its tail.
French, of course, is more convenient in this regard; everything is strictly divided by gender, and there is no such unpleasant neuter gender. One could say that people know how to speak beautifully.
