Good. We can't stop these barbarians, but if we can be even justa a mild and temporary hindrance to their twisted thirst for blood, then so be it.
Given that you, implicitly, support the excesses of the French Revolution because they helped create 'a wonderful regeneration of French politics and society', I think the you are the last person to be labelling people as barbarians or bemoaning their 'twisted thirst for blood'.
Those being executed in Texas just killed people, they didn't have the cardinal sin of being born into the wrong class.
