More than that, scapegoating is literally killing people on a daily basis. My wife and mother-in-law have just come from a wake of a young woman who just died of cancer, leaving 3 kids behind, one of them just 3-month old. University professors, who used to have the highest life expectancy, are dropping like flies. And chavistas keep blaming "the empire". As you say, how can we keep civility with these people?
Regarding global warming and the like, the government actually has, as the fifth item in their "plan de la patria", nothing less than "to save the planet" and you have to see the entrance of every town in Venezuela (the infamous rellenos sanitarios). Pollution in the streets is at an all-time high and with the exploitation of gold and other minerals down south, they have destroyed more hectares of land than ever before. Thus, cynicism is probably the only department in which we are a power force!
