I’m of two minds about that. On the one hand, I think it’s similarly arrogant to blanketedly attack any and all dogmatic principles as ludicrous and worthy of scorn. One might say that to hold that no principles are incontrovertibly true is, itself, a principle one can hold to be incontrovertibly true, and is therefore hypocritical.
On the other hand, specific dogmatic principles are indeed harmful to the self, the culture, and to society. Also, being a devout Christian myself, I’m well aware of the dogma that Jesus personally railed against and turned on its head because they completely missed the point.
I suppose it comes down to an issue of who is challenging certain dogma, their motivation for doing so, and their approach at doing it.
