"Socialists famous in this country, Mao, Stalin, Castro, Hugo Chavez and others, do not have the reputation for calm measured reason that Mr. Sanders enjoys."

I would submit that Mao and Stalin were not real socialists but more tyrannical.
Castro was a military man and somewhat of a dictator but he did a lot for his people
and his brand of socialism made Cuba a country with a workable modern healthcare system and a high literacy rate. US propaganda has painted a bad picture of Cuba purposely because they couldn't exploit it like they did other Hispanic countries.

What "others" are we talking about? Allende? The Sandinistas? Mossadegh? Be explicit please.

Also, morality is implied in the reverence for life in the above article. You don't
need religion to be moral and in fact religion often gets in the way of morality turning it
into hypocrisy.
