Grounded for a year. To severe?

[An Unknown Kevin]

So I posted a video game joke on facebook that supposed to be a good humored battlefield 4 meme. Now for the record, I wasn't threatening anyone in any shape or form and my friends all recognized the joke because they play the game. My uncle, in my eyes, over reacted and called my dad up saying I was threatening people with it and he called the cops, even though not a single threat was made. I then had to tell the police that I meant no harm I showed my dad what I posted and have been trying to tell him I wasn't trying to hurt anyone, but he took my phone, made me take down my facebook, took my xbox, and social activities away for a YEAR (Youth group, going to the movies with my friends etc.) I would be fine with a 3 weeks to a month but a year!? Is this an over reaction??
