What's your thought about civilian organizations that wear a uniform very similar to a military uniform?

I belong to several groups that wear military uniforms with modified insignia: Naval Sea Cadets (adult leader), Coast Guard Auxiliary, Civil Air Patrol and formerly California State Military Reserve. They all have their own ribbon awards as well. They are authorized by their respective services to wear them and I am proud to wear those uniforms and representing myself a a member of these respective groups; however, I still sometimes wonder if it goes too far since the public usually thinks they are actual military members. However, where I really think is really crosses the line are a couple of organizations that are formed to provide military honors to deceased veterans that wear modified Army uniforms and make themselves "generals" and "colonels" Yes they provide a valuable service and I know a few people in them. However, unlike the formerly mentioned groups I don't believe they ever had official permission to wear them by they Army and there is very little vetting/screening to people who join them. Prior military service is not required Many who join those groups seem to be "wannabes" either never been in the service or was in at much lower rank than what they are offered. I know its nice to have people in military-style uniform provide funeral honors, however if a military active or reserve group cant be found, American Legion and VFW have honor guard uniforms that they wear for them. What your thoughts about the wear of such uniforms particularly of the latter mentioned groups.
