Recognising that both the political situation and "society" were totally different in the run up to WWII, I can't help wondering whether a march similar to that being proposed on this thread would have had any effect. Like Minigundiplomat (and many of us) I lost antecedents in that war.
I think that both my grandfathers (one a bootie (1919 Murmansk), the other light blue (sandpit the first time round!) - both regulars prior to WWII) would have approved of a mass ignoring of Parliament & MOD MB - it is, however, a great shame that IMHO it will take at least an event like this before our political lords and masters "wake up and smell the coffee".
