I won't pretend I've read all 800ish posts spanning 14 years, but looking at the first few and the most recent, I think I see a fundamental problem with this thread.
The thread began with an argument that traditional karate isn't effective for self-defense because traditional karate training is based around the assumption of a one-on-one empty-handed face-to-face duel.
Nowadays the argument is that traditional karate isn't effective for self-defense because it doesn't involve competitive, aggressive sparring.
The problem is, "traditional karate" isn't one thing, and each person who is coming here to criticize karate is picking one particular approach to training that they don't like,
assuming that it represents all of "traditional karate," and then ragging on it. But traditional karate isn't one thing. It's not standardized in the way that "boxing" or "BJJ" is. When someone tells you they have a ferret as a pet, you know what to expect. When someone tells you they have a dog, it could be anything from a Scottie to a Rottweiler to a Newfoundland. When someone tells you they train at a boxing gym, you know what their training looks like. When someone says they train in traditional karate, it could be anything. It could be all about forms and one-steps. It could have lots of weapon work. It could have lots of sparring and plenty of competition. It could be some combination of these.
You can't pick the one approach that isn't what you want, declare it representative of all of traditional karate, and bash all of traditional karate. It's like how on the last page, this was offered up as representing all of traditional karate:
Sure, there are SOME schools that rely primarily on one-steps like that. But there are other traditional karate schools that look like this:

And there are some that look like this:
Or like this:
This entire thread is like a thread where half the posters are saying "I don't like dogs because they're small and yappy," and the other half are saying "I don't like dogs because they're big and slobbery." Both are criticizing very specific subsets of dogs, and acting like all dogs are like that. It's not that simple.
