Racism is not fascism. Imperialism is not fascism. Nationalism isn't facism. They are characteristics that sometimes or often lead to facism. Facism has a fairly explicit definition. Things can be a part of each other and overlap each other without being each other.
If I make a snowman, that doesn't mean that the carrot is a snowman or every snow sphere is a snowman. You can say that when you see me laying out the carrot with 3 balls of snow and a hat, it is leading to a snowman, but it has not always been a snowman.
But yes, facism is a huge danger and on the rise all over the world. Not even just in white western countries either.
