Sure, it may be a symbol of great evil perpetrated in the past.... but this is a historical replication and it's just not the same without it.
I agree.
I don't think that there is any reasonable human being who agrees with the darker portions of what it represents (read: holocaust), but I think that we are doing future generations a disservice by "watering down" the history.
Instead of hiding the symbol in an effort to avoid "admiration," it should be displayed in all cases as a reminder of just how terrible some of the crap that went on in Europe during the early 40's actually was... Just another example of how screwy political correctness has gotten.
No one seems to take issue with the Soviet H&C, never mind that Stalin made Hitler look like an amateur mass-murderer, and yet, for some reason, the old CSA battle flag is resisted due to slavery which, heck, it didnt even represent in the first place...
Ignorance results in these decisions. Education is, in all situations, far preferable.
