For those of you (outside the US) who were surprised (and upset) at the result of the recent US election, there is www.sorryeverybody.com. It's quite amusing, but serious in its intent.
And as on the web for every action there is an equal but not always apposite reaction, there is... www.werenotsorry.com. This isn't a spoof but a reaction and is not so amusing. But it's a great site for finding pictures of people with guns.
