This is rubbish! There was no one more tolerant than the Prophet salla allahu alaihi wa sallam. However, sometimes one may use some harshness but on rare occasions and not the norm! These people are not following the sunnah and they share some of the attribute of ISIS especially when it comes with dealing with those who differ with them!

I heard someone say the salaf were really harsh in refuiation agiasnt biddah and ppl of biddah, so we should be as well, so ppl like salfi publication is on the haq.
