That's only true in an academic sense. When a layman uses the term "political", they refer to discussion pertaining to things like how a formal government is run, comparisons between types of governance, government policy, etc.

While deciding what cookie to eat or what color your cat's litterbox is might technically be political in an academic sense, you're just going to annoy people if you try to tell them that those are political decisions. I have found that trying to force academic definitions into common use is confusing at best, annoying on average, and infuriating at worst.

An example of where a word's academic definition has no place in common speech can be found in "information". The informal definition of "information" typically is seen as referring to knowledge and the transfer of said knowledge. This definition allows you to gain information from a lack of something.

However, it is my understanding that the scientific definition of "information" does not allow for the aforementioned action, as "information" refers to the properties of physical matter. The result is that you cannot gain "information" from a lack of something. You might be able to come to conclusions based on a lack of "information", but you cannot actually gain "information" from a lack of something because "information" is inherently linked to matter.

Now. All of that said, this meme is related to something said at an engineering school, so on the one hand, it isn't entirely out-of-place to expect the academic definition to be used because it is an academic setting. Yet, on the other hand, it is an engineering school, not a political science school. As such, while OP should be aware that the academic definition of "politics" may come into play, it's also reasonable to expect that their professors and peers would mainly be using the common definition of the term.

However again, in my experience, trying to force academic definitions into casual discussion is confusing at best, annoying on average, and infuriating at worst. Please stop trying to do it. Thanks.

(Also, imo, genocide is like Schrodinger's Cat; it is both political and not political at the same time. Personally, I think it mainly depends on the depth of the discussion; but its "political" nature varies from person-to-person. Imo, saying that genocide is happening shouldn't be considered "political", but talking about why it is occuring is political.)

Edit: whoops, somehow my comment doubled, within the comment. The fuck happened there?

Edit 2: I swear I need to find a new phone keyboard, and I need to read over my comments before submitting. I'm finding a lot of stupid auto-correct errors, and it seems like they're becoming more common.

Edit 3: the reason I got hung-up on it, and I should have mentioned this, is because I often see "everything is political" used to justify bringing heavier topics into places where it's inappropriate (like chatrooms where people are trying to just hang out and have light hearted discussions).
