I seriously don't understand how people find moe cute. It's so completely artificial and inhuman that I just want to find a moe seiyuu and rip out her fucking vocal chords. I tried watching K-on and couldn't get through the first episodes with those autism noises Yui made with each step she took. It doesn't serve me as a "break from reality." It just reminds me of attractive female's ability to get love and affection just by existing, and it pisses me off whenever I hear anyone like digi expressing enjoyment from it.
I don't even find it cute like one would find a puppy or real life girl.
He's right though.
For example, pic related is very moe.
Moe is anything which provokes a strong positive emotional response in the viewer/reader. What is and is not moe is personal and unique to the individual viewer/reader.
Also I bet some time in your near future you will have an urge to watch K-On again and you will enjoy it.
