I am sure there is a lot of cross traffic between here and thedonald.win, myself included, although I only lurk there. I've been lucking since before the 2016 election, before reddit even banned the original subreddit.
Since the election there has been a huge number of election fraud posts, and while some of them certainly seem to have merit, there are plenty that don't. As a consequence I see posts that call for "low energy pedes" to leave, or Republicans (that aren't Trump supporters) to leave, etc. I fear that the signal to noise ratio is too low, and it makes it too easy for the MSM to ignore.
I have my own theories about what happened with the election, why, and how, based on what I've read, that I hope are reasonable, but my title question is an important one. It also asks other things. Is the Trump movement growing or shrinking? Are reasonable voices being driven away who really want to sort the fact and fiction? Are we all deluding ourselves?
The MSM still have some power, I don't deny that. "Caused Trump to lose", I'm not so convinced. But I won't deny that 4 years of MSM propaganda can cause some people to rally against the target. But that being said, you're looking at the problem wrong. They've never been this week. They weren't this week in the days of radio. The Mainstream Media hasn't been this weak since the late 1800's. Hollywood's never been this week. Never. These are wings in a long war, even if they're more costly than you'd hope.
As for your kids, you will make your children's future by hand. Don't rely on it to be crafted for them. They will have to fight for it, and you must teach them to fight.
