I like at least one GD lodge. (The local one; duh.) I like, for the most part, the OTO.
Both, of course, have a checkered and sketchy history; I find this happens with any large body of practitioners of alternate beliefs. That said: initiatory lodges serve their purpose.
I hold in contempt, on the other hand, any group of individuals that aims to suppress the individuality of the practitioner for their own (often malign) agenda. This can occur in either the GD system or the OTO if parasitic leaders arise and is the very reason, that while on their own they may be wonderful systems and even organizations, one should always remain at least somewhat wary and skeptical.
It is for this reason that I often frown on individuals or organizations that stress the suppression of the ego - which can be a valid path to enlightenment - especially if the practitioner never developed an ego beforehand.
Truly, the only 'valid' tradition that I regard with both skepticism and contempt despite the fact that it's valid, and has been shown to occasionally work, is Theosophy. During all my time hanging out with various occultists, witches, and free-style Shaman of a diverse range it has been Theosophists that time and again became blatant moralists and fanatics to the extreme, that I've seen make bizarre demands of their students, and that have been the first as an organizational body to threaten, cajole, and otherwise emotionally castrate nearly every practitioner I've met. I've met more schizoid Theosophists than in any other group (although the crazy Thelemites I've met actually rank second; I think it's because so many insane people go "Sex magick?!?! I can fuck my fellow practitioners?!?!?!" These people are the first I avoid).
As a rule of thumb that I personally hold, anyone that demands undue sex or money (initiatory fees for supplies and keeping a lodge housed not with-standing), is one to be distrusted. Further more, anyone that "pings the meter" (IE: the "bullshit" and "insane" meters perspective) gets uncertain glances. (90% of the Ecclectic Wiccans I've met "ping the BS meter" unfortunately; maybe I'm just hard on them.)
There's shady fuckers in this world, and I think stripping them of power is a pretty necessary prospect even today. It just saddens me to say that.
