Unfortunately, General Lee is also considered a white supremacist or at least a symbol of white supremacy by some groups on the left side of the spectrum. Hence, the continued efforts to remove Lee and other Confederate figures, which in turn will rile people up for other reasons (ie, people who might admire Lee as man or who cherish their local history). Of course, when they complain they inevitably get cast as being in the same lot with as the white supremacists, even if that isn’t their motivation for wanting to keep the statue around.
You need to calm down – in fact, a lot of people do. Yes, it’s true – the Left’s pursuit of identity politics that organizes people into tribes opposed to one designated outgroup that is the source of all ills in the pursuit of short term gain does and has produced to long term consequences of some members of said designated outgroup going "hey, wait a minute – we technically could be a tribe too…"
That still doesn’t make the organizers of this rally right. I’ve seen some of the pictures – I wouldn’t want to be associated with these idiots, even if I also wanted to protest the removal of Lee’s statue.
One final thing: do we even know who driver is yet, or what his affiliation is, or what if any statement he’s provided? Doesn’t it seem premature to automatically assume the driver was part of one group or another?
