Soros is a liberal who backs liberal groups, funds liberal politicians, and advocates for liberal positions. He’s also a billionaire, and billionaires comprise the 0.1 percent who destroy the little people - except for right wing billionaires, who are angels that walk the earth.
The right is demonizing any and every figure on the left. Creating hate and fear is the point. Soros is accused of funding the caravans because that’s this week’s issue. When next week’s issue comes around he’ll be accused of funding that. You can’t put thought into why; certainly the right hasn’t.
Just remember, every word the right says is a lie and projection. They are doing in reality whatever evils they wrongly accuse the left of. Since there are no evils they won’t do, we’re going to see ever larger and more nonsensical and more reprehensible charges hurled at the left and Soros.
