Examples of how the Salafi movement is ultra-conservative?

> The Salafi movement... is an ultra-conservative reform in the first half of the 18th century against a background of European colonialism. -- Wikipedia I've seen this claim repeatedly, but I'm yet to pinpoint in what ways the Salafi movement is "ultra-conservative" if it is even a correct label. Sure, some people have some extreme views, but it's hard to know how representative that is of the Salafi movement. **Question**: What are some illustrative examples of how the Salafi movement is ultra-conservative? I'm just trying to get a better idea of what precisely is being referred to when the term "ultra-conservative" is being thrown around.
