1000%. To me it feels like 99 times out of 100 it's a complete waste of time to not only figure out what collectivist labels one is using, but then getting them to define that label, because not everyone uses the same term the same way, etc. etc.

That time and energy could be spent discussing the actual topic at hand. I've 'debated' abortion with a friend who is very against it, but labels herself as progressive/leftist. Is it really worth the effort trying to unravel the apparent contradiction? What purpose would that actually serve, in the end? The topic at the time was abortion, so really, the only relevant fact about one politically at that time is what one's stance on that particular topic is, and why it is what it is.

This excessive and ever-more-granulated labeling is a waste of time at best, and an artifically-created wedge that drives people apart who are actually in agreement, at worst.
