Since I can't respond to your post in the Black History thread because I've been blocked from it, I'll answer you here.
I think they are, even if in name only. If someone calls themselves a Christian, I consider them to be a Christian even if it could be argued from their actions that they could only be Christian in name or membership only or what have you. Whether they are or not is between them and God. There are certain kinds of Christians who delight in telling other people they're not Christians, (while subscribing to OSAS or 'I'm a sinner but I'm saved,' thus reserving that assured redemption for themselves but not others). There are bad Christians who do bad things, like lynching and terrorizing innocent Blacks. History is clear on this.
If we are talking about everyone who calls themselves a Christian then you're right. There are tons of murderers in jail who have had "born-again" experiences and claim tey've turned over a new leaf. Many do this to get out of jail or obtain parole earlier
Many people in power claim Christianity for the power one can weld. This is less true than it use to be as Christianity in not popular in many states like California or New York. The Roman Emperors used Christianity as a means of control. Kings used Christianity to cement their own power.
Although most were converted peacefully, Christianity has been used as an excuse to conquer other lands. And no, I'm not talking about the Crusades, I'm talking about South America, Central America, and Eastern Europe. William the Conqueror gained permission from the Pope to invade England.
But one doesn't have to do much if any digging to clearly see that Christianity was not motivating their actions. The South's secession talked about such things as how they weren't able to bring their slaves with them to Long Island when they vacationed in the summer. One has to be really stupid to think that the South was inspired to go to war by Jesus.
Additionally, only the most gullible, dim-witted, or ignorant would believe that Jesus was the motivation to join or lead the KKK. But you go out of your way to insult Jesus by claiming his followers are KKK members. You could have said "I doubt they are following Jesus or they clearly are insulting Christians by claiming Jesus, but you didn't do that. You wanted to pin the KKK on Jesus. Why?
