An elderly Jewish man sitting inside a Palo Alto, California, Starbucks was viciously berated by a left-wing political thug because he was wearing an iconic Make America Great Again ball cap.

Rebecca Parker Mankey, the co-chair of the Bayshore Progressive Democrats, screamed at the man, calling him a “hater of brown people” and “Nazi scum.”

She posted a detailed account of the ugly encounter on her Facebook and Twitter accounts.

“I am going to publicly shame him in town and try to get him fired and kicked out of every club he is in,” the crazed woman wrote on Twitter. “I am going to go to his house march up and down carrying a sign that says he hates black people. I am going to organize protests where he works to make him feel safe as unsafe as he made every brown person he met today.”

She bragged about chasing the elderly man out of the coffee house, calling him a wimp.

“I followed him to the register while he complained about me,” she wrote. “Then chased him out of Starbucks yelling at him to get the f— out of my town and never come back.”

The victim, identified only as Victor, gave a detailed accounting of the attack to the Palo Alto Daily Post. The 74-year-old retired technical writer said there is an “atmosphere of fear” around being a Trump supporter in Palo Alto.

“People have always been allowed to wear a political button or shirt,” he told the newspaper. “Now to wear a Trump button is considered a provocation.”

Victor told the newspaper he thought Mankey was “on drugs or something.”

“I’m surprised that the Starbucks manager or someone didn’t call the police with this woman raving in the store like that,” he said.

He thought it was ironic that she would call a Jewish man a Nazi.

“I would call that just utterly irrational. Anyone with a high-school education should know about the Nazis and the Ku Klux Klan,” he said.

Mankey posted on Facebook that she was angered because other customers and Starbucks staffers did not join her political lynch mob.

Instead, conservatives rose up to defend Victor.

Mankey has since been fired from her job and she has resigned her position within the Progressive Democrats. Quite frankly, she ought to be charged with a hate crime.

Clearly, it is unsafe for conservatives to live, shop, or drink coffee in Palo Alto, California. The Make America Great Again crowd would be wise to take its business to a more tolerant part of America. Any red state will do.
