Even unrelated to Charlottesville torch walks generally have right wing connotations, as it was a traditional show of force by the Nazis. In Germany these days you mostly see them done as right wing rallies. As one data point, here[0] you can see NPD members calling for protest holding torches (during broad daylight).
The torches are used as a symbol - might be nothing, but paired with speaking out against cultural marxism it's more likely to be intentional than it otherwise would be.
I don't know, but I'm not giving them the benefit of the doubt since the mail server is fairly explicit if true.
And I still don't know what's wrong with a torchlight hike/march. (They call it a hike, you call it a march) It sounds like something I'd do.
