Is protest political?

In most cases, yes. Although some may be within different part of politics which makes the question confusing.

In all, I would say yes, and it depends.

It depends if your protesting for a political party. If it is a simple, for instance, pollution or climate change protest, it doesn't necessarily have to be!!
