Not only is this not a documentary and therefore against the #6 rule in the sidebar, it's a 3 minute video cherry picking a handful of negative examples to demonize all Trump supporters, a form of political propaganda to push a narrative.
A word of advice for all of the liberals that don't want Trump to be the next president...
Stop demonizing and attacking his voters.
Stop going to Trump rallies and physically beating up anyone who supports Trump. Stop calling them Nazis while you do so.
This may be a bit difficult for some to accept, but one of the major reasons why Trump got this far is really in protest to the constant liberal biased ciclejerking. By now you must have noticed how when Trump says something the left wing media freaks out over, it has no ill effect on him, in fact his popularity only rises. This probably makes you think "Oh all Trump supporters are racist Nazi KKK fascists, you can't reason with them...", however something very different is happening.
They are fed up with the insults and ad hominems being the dominant form of discourse from the left .Trump supporters are perfectly normal people whose political affiliation would be impossible for you to determine if they weren't explicitly expressed. When they hear Trump say something that is labelled offensive like "We're gonna build a wall", they think "that sounds a bit grandiose and unrealistic, however I do want someone who will stop illegal immigration" and they just put that idea in the back of their head.
But then the floodgates of harassment and ciclejerking burst open. The non-stop media insults, constant accustations of racist, misogynist, xenophobic, sexist, antisemite, homophobic and all the other buzzwords. They see their liberal friends posting on Facebook "UNFRIEND ME NOW IF YOU SUPPORT TRUMP YOU FUCKING NAZI RACIST IGNORANT BIGOT!". They see 19 year college liberals shouting "Trump is Hitler" all over places like Reddit. So just keep their mouth shut and this festers throughout the election cycle.
Yet the neverending circlejerking continues. The knee jerk emotional hostility to anything related to Trump makes people feel like they can't express their views in the land that prides itself on free speech and free thought.
By now they are cognizant that Trump is fighting against some very established political forces, and that the media wants to maintain that status quo. He lets people say what is actually on their mind. So every media attempt to demonize Trump supporters as the definitions of evil and bigotry, every failed drumpf meme, every single downvote brigade, every insult, every Hollywood denouncement just further solidifies their motivation. They see that their vote has power and they are ready to make the current status quo sweat. Whether Reddit wants to admit it or not, Trump has tapped into a genuine vein of discontent against globalism and open borders, perfectly valid concerns that shouldn't be dismissed.
If you can have a civilized discussion without instantly hurling insults and ad hominems, you may start seeing much better results.
