So as "a lawyer" you recognize the difference between a private, non-governmental entity choosing to not sell something because they don't support its direct or implicit message and "censorship", right?
As a "Jewish New Yorker" do you have the same feelings if the issue were people choosing to stop selling the Nazi swastika flag?
Pretending there is a benign motive behind the embrace of the Dixie Cross is a serious part of the problem. I believe people when they say THEY as individuals only meant it to be "pro-Southern" - but that is simply not sufficient once you understand what the symbol REALLY means in the context that it was appropriated for. It is NOT a tertiary symbol of the Confederate military, it is the banner of racists, segregationists and lynch mobs. Outside of a strictly historic context, which is highly limited based on the facts of history, it has no place and needs to be discouraged as a common symbol of "Southern Pride".
