You bunch of whiners! I can't count how many journals I see in my inbox of "Dammit da! Why the icons?! *piss moan* I hate you!"
Grow a fucking pair! They do this every year, it's an April Fools joke! They won't force you to keep it and they're gonna put it back the next day so just calm the fuck down! I absolutely hate Twilight but you don't see me whining about getting team Jacob, do you? I just laughed because I wondered how they were gonna top the mudkips that they did the time before last.
If you can't take a web site, A WEBSITE, changinng your icon for one day as a prank, then maybe you don't need to be on the internet.
