I collect WW2 Germanmilitary items but I don't collect or purchase explicitly Nazi items. There is a difference between the two but in some instances it can be fine. I don't say that others shouldn't collect Nazi items but I have no wish to collect explicitly Nazi items myself. I don't wish to attend an event, to be greeted by a fellow participant dressed as an officer in the Gestapo but, again that is a personal preference and I wouldn't go home as a result.
