Why is everyone trying to erase history all of a sudden? Because somebody felt bad?
Please don't hyperbolize. Removing the Confederate flags from public places like government buildings and refusing to sell merchandise with the flag is not erasing history. And I'd call the regular terrorizing and murder of black people under this flag far more than "someone felt bad". Apple simply took a way-to-heavy-handed approach here.
I totally understand the negative connotation and why that exists. And the fact that public institutions still fly it is "disturbing." But people against it should stop while they're ahead, they'll only see a massive backlash if this keeps up.
PS - I wonder how hard it will be for educators, civil war re-creationists, and similar to get a Confederate flag?
