The funny thing here is that RuboCop is an obvious pun on Robocop which is a satire of privatized police forces and corporate corruption.
But I'm not here to tell people what they should not be offended by. Telling people "you shouldn't be offended by X" is as bad as "we should keep politics out of software."
Instead of "keeping politics out of software" how about we try to listen to each other and be civil to each other even when we disagree? Which I think this posts articulates the argument for very well. I'm a lefty but this goes for all sides.
