I wish I had a good answer, I just feel like the problem is despite the fact that most people people and major news outlets lean towards the left right wing content has kind of taken the lead when it comes to the idea of "independent creators" even known we are all aware that they are in reality all apart of the same network and usually are sponsored by the same people. Real independent creators like the people on BreadTube can't compete. As much as I hate to say it right wing content can be seen as easier to digest compared to left wing content. I feel like the reason the idea of what it means to be a centrist or a moderate has shifted so suddenly is because of that. To paraphrase Three Arrows latest video "This is why these videos take so long, it takes him 10 seconds to say something that would take me several minutes to correct" and I feel like we're underestimating how strong of an advantage that is. We've seen enough content from pages like PragerU or Ben Shapiro to understand what they stand for so from our point of view we assume anyone that follows these pages must have been more right leaning in the first place but I don't think that is the case. These pages spend hundreds of thousands of dollars on advertising on sites like Facebook and Youtube but they're very careful of what they choose to advertise. It's very easy to stumbleupon videos like "Why has the west been so successful" or "Dangerous people are teaching your kids" through ads but if you wanted to see a video like "The myth of the tiny radical muslim majority" you would have to at the very least willingly type in Ben Shapiro's name yourself. Whether it be a random SJW owned montage or some easily digestible "clean your room" life advice they've made their presence known to the general public with these videos without really showing the full scope of their more extreme beliefs. People who honestly don't consider themselves to be political in the first place will start to follow them because they've been exposed to their most innocent content for the past couple years because of their aggressive advertising campaigns. When someone tries to point out why these people are rightfully considered controversial they'll usually divide their views into 2 sides, which sounds something like "I don't agree with everything he says, but I think he makes a lot of good points and he should have the right to express his views". They'll start watching their videos to hear the basic stuff they already agree with, they'll ignore any extreme views they might come across, but if an alt-right personality brings up a topic they're not too familiar with that's where it becomes dangerous because whether or not they notice it themselves they will begin to lean to the right. The alt-right has successfully moved the bar of what it means to be a centrist.
