I heartily agree with the writer, history is clear on this.  But she only refers to incendiary words from the right, not from the radical left (such as by BLM, to give just one example), so her credibility is diminished immediately.  Apparently railing about the tyranny of the patriarchy, as another example, is not cause for concern, however anything from the right end of the spectrum is evidence of a breakdown of previously accepted mores.  Very conventional, cliched point of view.  
Also, I've never heard anyone say seriously that "all" Muslims, every single one, holds any particular views - I think we all get that not every single member of any group ascribes to one particular view.  In fact what is usually expressed is along the lines of that many "terrorists" claim to be Muslim, which is a very different statement.  And I think the writer knows that, so her final paragraphs suggest she is being a bit disingenuous.
