Just look how they've done it in this country. They knew the best way to achieve their long-term goals were to take over the educational systems and the popular media. They have done this. Their first target was the baby boomer generation, so the leftists implanted themselves into the educational system, knowing that if they could influence the mass of young skulls full of mush that were to take power a generation later, they'd have the upper hand. Look at the spawn of that: Bill Clinton, Hillary Rodham Clinton, Barry Soetoro aka Barack Obama, Pocahontas Warren, Kamala Harris, and an entire rogue's gallery of leftist ideologues. And of course the media is hopelessly leftist.
We need to know and understand this if we're going to beat them. They know as long as we insist on an all-or-nothing, take-my-ball-and-go-home approach to countering their entrenched position, we're going to lose. The liberals will try to use that as a wedge to sow discontent and division ("See? Trump didn't do everything he said in the first 10 minutes of his presidency! You should throw him overboard!") Yes, we should try to make headway when we can, but we should not judge our people and our allies by whether or not they achieve everything demanded within the short time we often expect. Keep a steady hand on the wheel, and chip away and don't try to win a marathon by running sprints.
