I am a ghari-muqallid 'Salafi', I haven't caused any problems either. But yes, the Salafi methodology does unfortunately allow for easier twisting of the religion since it gives more freedom for interpretation. The ideology we call 'Wahabi' is an example of some of this twisting.
Regardless, sectarianism has destroyed us and will continue to do so, Taliban or no Taliban. By blaming one sect for all problems in such blanket statements, we're not doing anyone any good.
