It's because they're all divorced from the living experiences of workers (ie normal people) as well as being ultra sectarian. And since they're completely divorced from normal people as well as similar people of their subculture (because let's face it, that what politics degrades to without being connected to normal people), they start talking like cultist weirdos. The same process has also occurred to a lesser extent in academia. The only difference is that academia at least has a fresh wave of underclassmen and graduate students every semester and fosters some form of interdisciplinary collaboration through conferences.
Imagine if researchers in early medieval poetry only socialize with other researchers in early medieval poetry and do nothing but write polemics directed at researchers in late medieval poetry. They'll sound like fucking weirdos real quick.
