And you can blame this guy...
Or maybe this would be a more appropriate picture...
“In Expendables 2, there was a lot of vulgar dialogue in the screenplay. For this reason, many young people wouldn't be able to watch this. But I don't play in movies like this. Due to that I said I won't be a part of that if the hardcore language is not erased. Producers accepted my conditions and the movie will be classified in the category of PG-13." - Source
It seems Chuck doesn't want to be in a manly man movie, complete with harsh language and over the top violence, anymore. He has convinced the producers to lower the language and violence to get a PG-13 rating. You know, for the kids. All I know is the chances I'll like this movie have dropped quite a bit.
