It is an accomplishment of the leftist liberal media industry in North America and Europe that most people, when asked what political forces was the most murderous in history, will usually point to 20th century Fascism. It's an accomplishment because while it is generally accepted, it's also untrue.
In fact, if you tally the numbers in terms of ruined lives and mass murders, communism and its softer face, socialism, far outperformed the Fascists in terms of scale of depravity and length of time as an influential force. It is the never ending sympathy of the leftists who influence our cultural and historical awareness for those murderers that has created a society where the word "Nazi!" is an unforgiveable insult while "Soviet!" hardly raises a hair.
And so, enter Bernie Sanders. The senator who would be president is an unrepentant socialist, full of ideas that have repeatedly sunk economies and ruined societies. He swears allegiance to the political philosophy that, in its more extreme form, slaughtered tens of millions from the purges of the USSR to the Great Leap Forward in China and down to the atrocities of the Khmer Rouge in Cambodia. And for those who think that comparing him to some of the worst murderers in history is a bit extreme, then take a step back and try to remember why Greece was in the news so much. Hint, it wasn't over tourism.
What is Bernie's secret? Well first there's the endless soft indoctrination of the media. Donald Trump is being touted as a soft fascist and this angle is used to constantly vilify him. Bernie Sanders, on the other hand, is a soft communist and this makes him the people's hero.
There's also the legacy of the welfare state and its role in creating an entire underclass of people who think that they're entitled to a decent living simply by fact of having been born. They have been raised on the "The rich are the source of all your problems" mantra and readily flock to anyone who promises them more entitlements. Free college education! Free healthcare! Eat the rich to get the money for it!
And now Bernie, whose current religious affiliation is very much in question, is being called out for not being more "Jewish". Despite being the first Jew in American politics to accomplish what he has, he isn't waving the tribe's flag and there are those who are getting concerned about this.
Well should this be a surprise? After all, for the non-observant Judaism is very much an ethnic definition, possibly a religious one but not a national one by any means. Bernie is an American first, and really an American socialist first. His Jewishness might manifest in his eating borscht once or twice a year but not in a more meaningful way and if he is ever forced to mention it, it'll include some reference to social justice or another form of liberal bafflegab.
All this is secondary to his open political antagonism to Israel. Like a good liberal socialist, when given the choice between rooting for a democratic country where women and gays have full rights and a terrorist state where women are second class citizens and gays are illegal, he chooses the latter every time because according to socialists, you always support the perceived underdog even if that dog despises every liberal value you hold.
It should therefore not be a surprise that Bernie doesn't mention his Jewishness. It's not a factor to him. Only implementing the destruction of the American economy holds religious value for him.
