I should point out that both statements are true, depending on whether or not you are playing with amplification.

An electric guitar, unplugged, is perhaps the most forgiving variety of guitars, but play it too often unplugged and you'll develop bad habits that are painfully noticeable when plugged in.

I pretty much played acoustics exclusively for a couple of years, only to find out when I picked up my Les Paul that I had developed a lot of 'acoustic-only' bad habits that I had to unlearn. Little things like muting with my fretting hand -- great cheat on an acoustic, but basically acts like a double-tap on an electric.
