It is possible to identify hate speech. If Sadhvi Pagya says we should kick SRK to Pakistan, that is hate speech. If she said, SRK should go to Pakistan if he wants, then it is not hate speech. Someone says lets kill all Hindus, that is hate speech obviously. Someone says let us call Prophet Mohammed names, not a hate speech, because it does not cause any material or bodily harm to any muslim.
Ohh I think you are taking 'hate speech'(as a literal phrase) to mean any speech with words of hatred in it. 'Hate speech' is a legal term, very well understood. Blasphemy does not qualify as hate speech. All countries ban hate speech and different countries might have different exact definitions. But India's is the loosest, if someone is hurt a ban can be expected.
RUBBISH !!!
Sadhvi Pagya saying SRK should be kicked into pakistan IS NOT HATE SPEECH. That is her OPINION and She is ENTITLED to her Opinion.
Asking others to kill SRK is hate speech.
Hate speech is provoking other to BREAK THE LAW. Not provoking others to hate others.
