Ah yeah, the old 'The left is as bad like the right' narrative ...
The problem is that a lot of people confuse retards for leftists, but to be honest, a lot of us leftists are not very fond of those SJWers and PC-retards runing around playing professional victims either. Those people are a minority. Where as the right, has in many ways rather clear motives that are common among many of their groups, like xenophobia, closing borders to refugees, blaming whole religions/cultures/nationalities for the actions of minorities and so on. If we just look at Europe for example, you will have a hard time to find the same kind of groups like
Identitarian movement or the AFD or someone like Orban on the left, leftists today are for the most part social democrats. Infact in Germany Die Linke, is a democratic party following social polocies of the 60s and 70s, they are not socialists (MLPD) or even Communists (DKP). However, alt-righters and right wingers are just repeating the same xenophobia that was wrong 40 years ago and is not geting better, just because they word it differently and trying to mascerade their discrimination and nationalism as 'patriotism' and 'protecting' of their culture.
Does the left have its retards? Absolutely, but their policies are for the most part pretty acceptable, not engaging in wars, treating people as individuals rather than cultures or groups, equality, egalitarianism etc. With the right though, you have retard policies just as how they have been thrown around 150 years ago. Particularly in Europe but also the US.
