Jokes aside:
Yes, it's an unpopular opinion. And yes, this is a kind of paradox idea that seems to be at home in only one country in the world. And we being a rather international community, it is inevitable that eyes pop and words of (hopefully only) surprise are spoken.
The claim still stands that foul language is an integral part of the hard and cruel world of the Walking Dead, and only the popular TV series likes to tell us otherwise for obvious reasons - censorship reasons.
The designers have decided to add swearing to their game, and I guess it was a pretty conscious decision. In other adventure games the conscious decision was not to do it (a notable example is the original Maniac Mansion, where Tim Schafer wanted to put swearing in just for the heck of it and seemed to have been stunned by the simple question: "Does it add anything?"). I can respect both decisions.
In any case, the last thing we need here is an exchange of insults on the topic of swearing.
