They think their testimony will make Congress "do something" to stop illegal immigration. If anything, that testimony will prompt Congress to enact amnesty and open the borders more. White folks just don't get it.
Imagine "our" ruling elites had two options to choose from:
1. 99.9% of the Earth's White population - men, women, and children - all Whites except for the top White elites themselves will be painfully killed, OR
2. A single Colored person experiences one microsecond of inconvenience.
You had better believe that all the elites would pick #1. Not only would they pick #1, they'd all fight with each other for the honor of enacting it. Imagine Merkel, McCain, Cameron, Sarkozy, Miss Lindsey, the entire political, financial, and media elites of the "West," all fighting and clawing at each other to be the first to "push the button" to enact #1, and spare the poor "person of Color" the slightest discomfort or inconvenience.
Yes, I know, you'll say this is over-the-top hyperbole. But doesn't it capture the essence of reality? How do the elites actually behave? Don't they consistently ignore White interests to favor Coloreds? Don't they respond to stories of illegal immigrant crime and depravity by campaigning for amnesty? Aren't they attacking Trump (a rare elite who is a bit more truth-telling than the others) for simply stating the facts on illegal alien crime? Is the scenario outlined above really that far-fetched?
