I disagree.
I share your thoughts in general terms--that the NO was ill-concieved, implemented without sufficient pastoral judgment, and has subsequently been horribly abused by variously-agenda'ed groups of termites, snakes, pederasts, anti-nomians, and other scum-sucking detritus. Clear?
However, your statement above presumes that SSPX has valid arguments on several fronts, which is inaccurate. They do not, as has been shown here (and in far more pacific journals) countless times.
Thus, "bashers" are, in fact, defenders of the Church, contra your assertion.
By remaining faithful to the perennial magisterium, they have brought on the excommunication, afaik, thats not possible.
