You are mixing up hate speech laws and blasphemy laws. While hate speech laws are pretty common in EU, blasphemy laws are vestige of the past, and in just few EU members (e.g Austria and Germany).
I mean what is the functional difference between a hate speech law and a blasphemy law? Seems it's just a subset of hate speech and is relevant to the conversation.
But legally they are two different things. Just because you feel it's a subset of hate speech that doesn't mean it is.
In a lot of countries with hate speech laws, but no blasphemy laws, this would be allowed. She did not say anything about the people following Islam but about a religious figure, these are not the same thing.
They have distinct targets. Hate speech laws forbid speech against groups of people, not against ideas and religious characters. Verbally attacking christians or muslims may fall under hate speech laws, while verbally attacking Christianity, Islam, Jesus or Mohammad does not. But it would fall under blasphemy laws.
