I've not suggested that they have behaved abominably, quite the opposite. I've said that these groups do not use the bible and Christianity to justify their actions in the same way that ISIS uses Islam and the Koran.
Are you actually making the argument that they do? Seriously?
I am suggesting that they always did, very publicly and with no reticence or doubt. They attacked Jews because they rejected Christ, they attacked Catholics for not being protestants and they take an oath to uphold Christian values. What more do you want?
I am not saying the current day clowns do the same. I don't know anything about them.
And I am not saying they were good, devout christians. Just that they aligned themselves with Christianity. It is a matter of fact.
