So you believe "shinto"
is an English term? Or that English is a "phonetic language"
Oh no, I don't think Shinto is English. It comes from the characters "shin" and "tao" I believe English is phonetic and does its best to phonetically spell out those non-English characters.
Please reference my source for why I chose to spell it the way I did. Also the book "A Life In Aikido" by Kisshomaru Ueshiba used this spelling,so forgive my ignorance if people are angered by simple phonetic spellings.
In the end I think it is the difference between the word "gray" and "grey"
