There is a strain of bigotry in American politics. It’s not limited to the Klan, white nationalists, or the “Black Israelites.”

It’s among a group usually celebrated by the left. It’s long been there, and it has surfaced many times in recent years. Over the past month, it’s again emerged from its polluted depths.

I’m talking about the prejudices of the Democratic left. Here are three glaring examples.

Anti-Semitism

Minnesota’s Ilhan Omar recently claimed that congressional support for Israel is driven by money from AIPAC, the American-Israel Political Action Committee. She also tweeted that congress’s support for Israel is “all about the Benjamins baby,” She essentially accused supporters of Israel of taking bribes

Then there’s Michigan’s Rashida Tlaib. As soon as she was sworn in, she “affixed to a map in her office a Post-it Note reading ‘Palestine’ and pointing to Israel.”

These two are not unique. “According to a Pew survey, in the dispute between the Israelis and Palestinians, only 27 percent of Democrats side with the Jewish state. Almost equal numbers of Democrats side with the Palestinians, and the subset of left-wing Democrats are pro-Palestinian by almost two to one.”

Underlying this attitude is the disgusting belief that Jewish Americans simply buy political influence among cynical politicians. Having worked in Congress for many years, I can speak to the fact that this is a lie. Many Members of the House and Senate back the Jewish state because of (a) deep faith-based convictions and (b) simple decency.

A small ethnic group, six million of them slaughtered like animals only a few decades ago, deserve a homeland. Safe and secure and their own. Indeed, they have one. And it’s a free, flourishing society that gives its Palestinian citizens more rights than they would have in most Arab countries.

That many on the left can’t or won’t see this or are so easily confused about the realities of the Middle East is pathetic. Or just plain evil.

Anti-Business

Can anyone say, “Amazon”? A company that would have paid the 23,000 New Yorkers it was planning to hire at an average of $150,000 annually? Even Andrew Cuomo was indignant at “Democratic Socialist” Alexandria Octavio-Castro’s supporting role in ruining opportunity in her blighted congressional district. This victory of the left reveals the true face of iron-fisted fascism.

This has been a growing trend for years: Democrats assail “Wall Street” and big companies and the very idea of profit. They then wonder why Bernie Sanders and his ilk are squeezing-out moderation in their party.

But there’s something else that’s often overlooked. Calling corporations of any size greedy, predatory, loaded with “fat cats” who deny their employees anything but gruel is demagoguery. Or, to use another but even more correct term, plain bigotry.

The left professes to love the “working man” and small business. Are they so dense they don’t realize that no corporation exists by itself? Companies like Boeing, GE, AT&T, and Microsoft have thousands of sub-contractors who make the parts they use to assemble their complex products. And the jobs they provide themselves support countless other jobs — from car dealers to hair dressers to family farms.

This is all lost on, or unimportant to, the purveyors of the left’s brave new and essentially anti-American world.

Anti-Christianity

Where to begin? Dianne Feinstein, Kamala Harris, and Mazie Hirono have all distinguished themselves in recent months with overt anti-Catholic bigotry.

Last year, Evangelical and Wheaton College grad Russ Vought was pilloried by Bernie Sanders during a Senate hearing. Why? Because as an undergraduate, he had written that faith in Jesus Christ as the only way to God. Sanders concluded that “this nominee is really not someone who this country is supposed to be about.”

Then, of course, there’s the ongoing bullying against Christians who continue to affirm that marriage is intended to be the union of one man and one woman, for life. I really don’t need to catalog such instances, especially given their frequency.

Where This Leads

Bigotry leads to violence, at least when coercion and oppression don’t work. This is the witness of history. Ask the families of African-American lynching victims or Holocaust survivors. Learn about the Armenian genocide.

Anyone who doubts the resolve of the far left is kidding himself. But let’s hope they are overplaying their hand. Hope and pray, that is.
