Which you get exposed to depends on your echo chamber. Echo chambers don't share the rational arguments of their opposition because nobody wants to think the outgroup has a point.
That George Soros is funding a migrant caravan of invaders is a conspiracy theory. This theory was amplified by both the President and Fox News, so it's hard to claim it's not even a mainstream theory.
Unfortunately their go to right now, and probably for the next x number of years, is the guy who shot up the Republican baseball game. No doubt there are extremists on both sides, one side just seems to have way more
There are a lot of these cases, where a violent person is unjustly tagged as "the right".
When someone can't be crammed into that mold, they are dropped from the news. A prime example is the youtube office shooter, who was a female muslim immigrant. As soon as the demographics became clear, the news dropped the story like a hot potato.
Basically, the news wants an attacker who looks like their stereotype of an NRA member and/or Trump supporter. Anybody else is not deemed newsworthy.
That trip is not free.
Soros certainly has a history of funding exactly that sort of thing. For example, he paid to have boats pick people up right off the coast of Libya and take them to Italy. It would not be the slightest bit surprising for Soros to fund a mob of thousands to invade the USA.
If not Soros, then who? (and who paid that group, and who paid the payers... and does it not lead back to Soros?)
This sounds like if one cannot pinpoint the supposed funder (and prove that they act alone), then you'll feel free to assume it is Soros? This is nonsense.
