Granted, I'm dyslexic and apparently dyslexia only affects characters which are phonetic. This has also been my experience and I love Chinese characters in Japanese text because it's much more comfortable for me to read. So that's why I might prefer symbols.
I'm wondering, though, why people dislike symbols (and I know it's a very common thing). It's just like any other letter, except that it has a meaning. I wonder, it is because it's hard to read phonetically (just the opposite of my problem)? Whenever I've asked people they say "Symbols are ugly", which is kind of an unhelpful response. It's like saying, "I don't like it because it is unlikable". I hope someone has a slightly deeper insight into the reasons.
