I totally disagree that electric guitars are easier to learn on.

For a start, an electric guitar will amplify every single unwanted noise such as when your fretting fingers scrape a string, or when your pick hits one too many strings. You also need to develop fretting hand techniques for muting strings, etc.

Acoustics are more forgiving, in general, and also take a lot less setting up before you can play it. No leads into amps and such.

You also develop better technique and finger strength on an acoustic.

Obviously, though, if your intention is to only play thrash metal or any other high gain rock, then definitely don't waste time playing acoustic guitar; get an electric with hot pickups, distortion pedals, a loud amp; and learn to avoid unwanted noise right from the beginning.

The above is just my opinion, but I'm an ex-folkie, so what would I know. I only got into electrics around 15 years ago, then discovered the strange world of effect pedals.....
