The holocaust should be remembered. It should be remembered in the proper context with respect for the victims. Comparing it to trivial contemporary events is not a fitting form of memorial, it is simply offensive because it serves to minimise the tragedy of it.A reminder of the Holocaust is not minimising it. It's reminding people what people and Governments are capable of is left unchecked.
And I don't see how mentioning the Holocaust and keeping a spotlight on it, serves to minimise it. Would you rather the Holocaust wasn't mentioned at all?
