The narcissism of small differences between hate groups desperate for attention, any attention

An interesting pair of posts by Brendan O'Neill. First:

It's becoming so clear now why the war of words between SJWs and the new white nationalists is so intense. It isn't because they have huge ideological differences -- it's because they have so much in common. Both are obsessed with race, SJWs demanding white shame, the alt-right responding with white pride. Both view everyday life and culture through a highly racialised filter. SJWs can't even watch a movie without counting how many lines the black actor has in comparison with the white actor so that they can rush home and tumblr about the injustice of it all. Both have a seemingly boundless capacity for self-pity. Both are convinced they're under siege, whether by patriarchy, transphobia and the Daily Mail (SJWs) or by pinkos and blacks (white nationalists). Both have a deep censorious strain. And both crave recognition of their victimhood and flattery of their feelings. This is really what they're fighting over -- not principles or visions but who should get the coveted title of the most hard-done-by identity. They're auditioning for social pity. "My life matters! My pain matters! I matter!" The increasing bitterness and even violence of their feud is not evidence of its substance, but the opposite: it's the narcissism of small differences.

Then later in a different post, he illustrates the parallelism of these two racist totalitarian groups:

"You are a white man. Check your privilege. Stay in your lane. You will never understand black people's lives or experiences. You're all about whiteness, that's how you're conditioned." -- SJWs

"I am a white man. What a privilege. I'm going to stay in my lane. I will never understand black people. I'm all about whiteness, it's how I'm conditioned." -- White Nationalists

The proper response from a classical liberal is to ignore their temper tantrums and prosecute them for their violence.
