Discussion on answer by Lilienthal: "Offensive" bumper sticker on car

It's a sticker. You're not talking about fighting segregation or a corporate thought police here. The OP and a few of the commenters like yourself seem to want to argue that the right to be an arsehole somehow trumps an employer's right to determine the kind of workplace he wants and the kind of behaviour that is and isn't acceptable. Frankly, I don't get it. Is this really a hill worth dying on? Are your principles so strong that they won't let you be considerate of your own colleagues?

@Random832 I really don't see why you consider this request unreasonable. Several employees find the bumper sticker offensive. I personally don't care about profanity but many people do, particularly in the US. It's a sticker and one that's childish, immature and utterly inconsequential. It's perfectly reasonable to ask someone to remove it if it means that multiple employees will no longer feel offended every time they enter the office. If left unchecked this kind of thing will cause bad blood in the office so it should be nipped in the bud.
