It's fair to say that an explicitly, aggressively political leftism is desperately needed in the world today to counteract proto-fascists and neo-fascists. But any version of that you get that also hates "liberal multiculturalism" will be a cure worse than the disease.
Nope. Your claim that liberalism and fascism are the only options and that the former is the only way to fight the latter is wrong. In fact liberalism and fasciam actually reenforce each (anybody is nowadays a politicall correct multicultural liberal, even a hardcore Thatcherite like Cameron.) other so the only way to actually fight racism, xenophobia, fascism and so on is via left-wing solidarity and not via fake (the worst racists are probably PC upper middle class folk, they like blacks as long as they live far away) poltiical correct liberal multiculturalism.
There are numerous examples for this. The European societies reached their historically most liberal phase during the 20s, shortly before the rise of fascism. Nowadays we face a rise of xenophobia despite the clear dominance of liberal multiculturalism. Same with Islamic fundamentalism, it is not becoming more powerful in spite of Western liberalism but because of it. Admittedly the following examples are more about real politics than pure ideology. Everywhere in the Middle East you see the same pattern, a decline of the left and the rise of fundamentalism with the West often being the catalyst, be it Afghanistan, (fighting communists with mujaheddin), Palestine (Israel having been happy about the rise of Hamas because it led to infighting with the secular Fatah) or Iraq (a secular dictator was exchanged for Shiitte and Sunni miltia violence that has gone on for over a decade now).
Of course I do not expect somebody liek you who claims that any left-winger who is against political correctness to understand any of this. You are too deep in this binary 'either liberalism or fascism' world.
If you meet somebody from another culture the worst thing to do is to play the multicultural game of "what interesting food/music/traditions you have". The best way is to either ignore cultural idiosyncracies or mock them, you own and those of the other guy. Or in other words, the best way to fight racism is via using it on everybody (this is e.g. why black people use the word "nigga", to use it all the time such that it loses its racist meaning).
You can also see the differences between distanced, politicall correct liberal multiculturalism and actual solidarity/friendship via analyzing how you behave when you become friends with somebody. You start to playfully insult each other and so on precisely to signal to the other that you are beyond the superficial level of distanced politeness.
I am not saying anything original here, Zizek has elaborated on how liberalism without a left leads to fascism in numerous books and articles. Not that it takes a genius to understand that a world without a left will inevitably tend towards the right.
