Of course PDA is accepted and has not been banned ever. Not even in Argentina (or other countries recently under a dictatorship). It was, maybe, seen socially as a bad conduct, but not ""banned"". There were no sanctions or fines applied. Also, even if it can bee seen as a display of the newly gained freedom (perhaps the music video ""Zoom"" by Soda Stereo can be an example), it cannot be considered a ""patriotic"" act, particularly in Argentina were it was the Junta who used terms such as ""patriotism"", ""nation"" and even race to promote their values.That section needs revision.

In Chile, another country ""recently"" under a dictartorship, there has been a large amount of discussion in the mainstream media regarding ""emo kids"" (just teenagers i'd say) virtually ""taking hold"" of public parks in the capital city where they involve in drinking, smoking and many forms of PDA. Even though the practice is widely accepted, the debate shows that the subject is not so pacific.
