In European countries that criminalize hate speech, changing the targeted group doesn't make it less illegal. Left-wing extremists attacking right-wing extremists are most definitely prosecuted. Turns out that not tolerating the intolerant doesn't mean you have to get violent.
If you change the words in someone's sentence, the sentence changes it's meaning. Nothing is new there. Regardless, to your point I would like to bring up the paradox of tolerance[1]
