1. He thinks radicals don't have any meanings and are equivalent to letters in English.
I think you only read the first two sentences of
Kanji Facts | KANJIDAMAGE, if you read the whole thing, his point seems to be that most radicals don't give you a useful indication of the meaning of the word often enough to be useful. He lists 39 that he thinks *are* worth knowing for their meaning. If the others don't help, may as well just think of them like letters.

One thing I'm curious about... before you edited your post, your first point was that you wanted to know what qualifications the guy behind kanjidamage had,
and pointed out the Heisig has a PhD. I guess you probably looked into it further and realised that Heisig's PhD is in philosophy of religion and he has (
as far anyone can tell), no formal qualifications relevant to teaching kanji. Now that you know this, do you think less of Heisig or his method?
As I understand it, Heisig is a guy who learned Japanese as part of his "day job", and came up with a method that worked well for him and he published it so
other people could benefit from it if it worked for them. Isn't this likely what the kanjidamage guy is doing?
2. there are 2136 joyo kanji, he cut out 100 and left with 1760 kanji? How does the math work here?
He says he cut "over 100 kanji". Last time I checked, 376 is over 100. But that site has been around since before the latest additions to the Joyo list ( says copyright 2009-2012), I'd guess he wrote that when there were 1945 Joyo kanji, which was up until late 2010. 1945-1760 = 185. Which I believe is also over 100...
3. He only find 1760 or so useful? How did a non-joyo ナ?ツュ (rape) made into his list and yet he cut out more than 400 other joyo kanji? Gives you an idea the kind of material this guy is into....
I can only assume you're joking here, because if you're really saying that if someone teaches that a word exists it's proof that
they're "into that kind of material", then that is probably the most ludicrous ad hominem I've ever heard. You should probably call the cops immediately on the editors of Webster's and the Oxford English Dictionary, you wouldn't believe the range of sick and illegal things those freaks are into!
In fact, he tags that as a "dangerous" word, as defined here
Offensive, Embarrassing, and Vulgar Kanji - ABU | KANJIDAMAGE . Seems to me like he's sensibly pointing out these words exist and you should know to be wary of them.
The site is basically a plagiarism of "remember the kanji" and a
koohii. A lot of different materials you can readily find on the internet and mixed up together into which he calls his kanjidamage method.
Really? As far as I can tell the only similarity between Heisig and Kanjidamage is they both use mnemonic stories. Kanjidamage's mnemonics try to be silly in order to be memorable, they mostly revolve around crude humour, slang and 80s pop culture references. Is there a lot of that in Heisig? Can you give an exmaple of something you think Kanjidamage plagiarised?
I haven't tried koohii but from the looks of it, it seems to be a flashcard spaced-repetition system, which Kanjidamage is not. I don't see the relevance?
