I don't find a problem with Taheri saying what he says.
I don't find a problem with others trolling on what Taheri said.
But I do find problem when people try to engage the government in it, and try to ban or punish him for what he said.
That something is a "Bid'a, Munafeqi, not-Sunnah" has nothing to do with our justice system or our government.
I rather appreciate Taheri's stand on it "If law enforcement want to monitor what I say, let them monitor and I am not a bit concerned about it. And if they find anything illegal, let them do whatever they are supposed to do."
This attitude of 'I don't give a damn on what others say' is something that I can learn from.
