Totally. Those labels are instant mind-killers and in my book they are tools of the Dark Arts. When someone calls you a "socialist" or "neoliberal" or whatever, they imply you believe everything some ideology has to say, so they can go ahead, point any random weak point (every political ideology has some) and call you a moron.
This is so totally dumb behaviour, that I can't even begin to describe it. What's equally dumb is assuming that if you agree with some group on one thing, then you should also agree on everything else.
Basically - for me, giving yourself a political label is a sign of subpar thinking. Giving others political labels is disingenuous.
"mind-killers" and "Dark Arts" are self-describing labels, though. They don't avoid being political rhetoric just because they were coined by a guy who purports to be opposed to political rhetoric.
