Your claim that you're not anti-Hindu/anti-Krishna is absurd. You claim Jagad Guru Siddhaswarupananda (Chris Butler) is not a bona fide teacher in a bona fide Hindu disciplic succession (parampara), but you accept that certain other Hindu teachers are bona fide.

Since you claim to be an authority on Hinduism and believe you're qualified to decide who is or isn't a bona fide Hindu teacher or guru, then you need to put forward your background that makes you an expert in the subject of religion and most importantly your expertise on the subject of Hinduism. 

Secondly, you need to put forward scriptural or other evidence substantiating your claims that Jagad Guru is not bona fide, along with evidence to establish what, in your view, makes the other "Hindu gurus"  bona fide.  In other words, compare their teachings and point out what Hindu/yoga scriptures their respective teachings align with or don't align with to illustrate how you concluded which Hindu gurus are and aren't bona fide.
