The law in which country? All countries? Do I have to avoid uploading depictions of Mohammed, or insulting statements about the president of Turkiye?

ps. I like my vacations in south Turkey.
I normally take a bit of a "dim" view of generalizing certain behaviors to an entire nation's population, but this one's spot-on for certain, and I say this as an English speaking U.S.-born citizen that's lived here all my life, and pretty much grew up "online" (had Internet access since the early days, and even before that I was on local and "long-distance" BBSs quite frequently).
When this specific sort of assumption is made online or in writing / speech, it's almost always "The U.S." Totally too many folks here have a "weird world" inside their mind where there is only "here" and "everywhere else", and "everywhere else" only really matters at all if it somehow "infringes" upon the personal-space of their social-media mandated "rage button".
In effect, in a world where extradition treaties exist, the law you're subject to is the sum of the laws of all the countries your country has agreed to mutual extradition with.
(And strangely enough, I believe this is even transitive. Presuming countries {A,B,C} which have extradition treaties AB and BC, if country B can get you extradited from country A for crime 1, then country C can get you double-extradited during your detainment in country B for crime 2 — even though country A may have never signed any treaties with country C!)
But even ignoring extradition... when speaking of international diplomatic relations, the law-in-practice of "whatever country you're in" is often not the law-as-written, but rather "whatever it takes to make a foreign country happy." I.e. if a foreign country wants you punished — and your own country isn't so powerful as to be able to just tune them out — then often you will be slapped with whatever local law your own country can make fit, to get the other country to calm down.
I brought up the president of Turkiye for a specific reason: the https://en.wikipedia.org/wiki/B%C3%B6hmermann_affair , where a German who wrote an insulting poem about Erdoğan, was charged with a [rarely used, archaic] crime by the German government, after the Turkish government basically sent a strongly-worded letter to the German government implying that their relations would be damaged unless they "did something."
(Though, pleasantly, after much outcry from the German populace, the law they used to try to punish Böhmermann was challenged and repealed: https://www.npr.org/sections/thetwo-way/2017/01/25/511611581...)
