They actually understand it quite well. It represents an enormous threat to their effort to undermine our sovereignty. Liberalism is actually Communism. Like Khrushchev said, "You Americans are so gullible." President Trump may be our last best hope for defeating and eradicating liberalism once and for all. The democrat party is the Communist Party. WE must face that reality and deal with it. "The tree of liberty must be refreshed from time to time with the blood of patriots & tyrants. it is it's natural manure." -Thomas Jefferson
They understand fully. It's just that Democrats are wired to be in opposition of anything Republicans say, just like Republicans are wired to be against anything Democrats say. Hence why nothing ever really gets solved with this failed bipartisan system.
Demorats are socialist and communist. They hate you if your a Republican..They're against everything you're for. They hate everything this country was built on. They're thieves and liars and want all your freedom's taken away. Never forget, they are your real enemy
