The Alternative Right has been formed as a result of the left's incessant need to ignore the concerns of the working class demographic, hence allowing vocal minorities among the disenfranchised to attach themselves to radical movements promulgating against their own socioeconomic interests. I'm not a fan of Donald Trump, nor am I a fan of Milo, but both have managed to manipulate the working class vote by preying on their insecurities. If we, as so-called progressives, are unwilling to comprehend the others' concerns then we are adding to the discontent which has led the western down a path of political extremism. In saying that, however, the regressive left has become one of the heinous political movements of modern times, notably because of their unfounded appeasement of political correctness and their willingness to stray from classical liberalism to pander to ethnic minorities and their own skewed agenda.
I wouldn't consider myself left wing, but I do bot agree with the alt-right. I'd recommend people listen to Ben Shapiro (Conservative), Dave Rubin (Liberal) and Sam Harris (Moderate) if you want to have a fresh perspective on world events and geopolitics.
