Someone clearly doesn't know the definition of hate speech.
Who does? it's subjective.
The extreme cases might be obvious such as ISIS propaganda or KKK type material but there'll be a lot more grey areas where it's a judgement call, I believe one of Facebook's criticisms of this law before was that they're being asked to do in 30mins something that would take the legal system months in most cases in deciding whether something breaches so called "hate speech" laws. Social media websites are just going to end up pulling anything that gets complaints/flags and is mildly questionable for fear of being fined and we know which end of the political spectrum loves to take offence at every little thing and shut down opposing views.
