I don't think Salafi people are dangerous. Since reverting, I've found a Salafi friend who I can count on for ANYTHING. Yes, he can be a bit strict in his views, but he never lies to me about something and if I accidentally do something haraam he won't sugar coat it to give me false impressions it's not a big deal if it is. Frankly, he follows the Quran and Sunnah better than most people I've met. For these reasons, I don't think Salafis are bad. They're people just like we are.
