Well, its not exactly my idea. Until last year i used to use rub on letters straight onto the wood. But it was a pain in the butt and i wanted somthing more colourful with the flags and badges. I actually saw what others were doing and adapted it for my own ends.
As for the flag, well i have one of those myself. No, i don't think it means your supporting those ideal's or causeing offense as its in your own private space. I assume you also have an old Soviet flag. I always find it strange that people get so upset at the nazi insignia but will display the Hammer and Sickle without a second thought.
I have done a couple of builds recently of vehciles in SS units. Instead of the eagle in the shield i have put the SS sigrunes. I have never had any come back, even when taking them to the model club. Its all part of the history.
I have pretty strong views on free speech and free expression,which of course i won't go into here. But if you want to display the flag, then thats your choice.
I am a Norfolk man and i glory in being so
