Critical discussion are not hate speech. Yes, there are Muslims who are wrong, but that doesn't discount the entire problem.
The only reason antisemitism is brought up is because it is a familiar topic which many people understand yet they claim to not understand Islamophobia which shares many similarities but has a different target. It can be used to put things in context. For example, holocaust denial is clearly antisemitic but is it a crime? If someone creates a website that claims the holocaust never happened, we should clearly condemn them but should we throw them in prison? If they commit a crime like attacking a place of worship then that can also be antisemitic and criminal so they should be thrown in prison. It helps put things in context.
