Spoiler, they don't, they're the least happy people you can imagine, while most people keep their sad and angry weirdness to themselves chuds and other reactionaries are leaking it all over the place so they can be seen, so at first glance it looks like a strongman act and a better way of handling irony poisoning, especially to Murikkkans and others that love humor outrage at the cost of others, when really its not much healthier than bottling, if not worse since they harm others aside from harming themselves. They just lack social awareness to see how fool they're acting and it doesn't look badass, its like a baby having a tantrum because they were told no. The baby feels no shame for their tantrum.
