No, that conflict was about secession and slavery (and regional issues). All of that was moot 150 years ago.
The KKK was about something else. And then it died out.
The threat who poses? The few w.s. left? Most of the leftards on this site, are constantly talking shit about how ALL whites, or ALL not left leaning whites, are "cucks" and "weak" and "old" and "dying off".
But every now and then, suddenly they become this big danger.
I've seen lefties ridicule whites for being cucks and weak IN THE SAME SENTENCE as they whine about what a danger they are.
You seem to be conflating a lot of issues together over a long stretch of time, to justify attacking people today.
