Your info about "Contramano" is partially wrong. It opened in February 1984 AFTER the democratic government was sworn in on December 1983. The army never went in with guns walking between patrons because when [it] opened they were back in the army barracks for good. The police though used to come in, put in strong lights, cut music and in an abusing way ask IDs before all type of discriminating laws were abolish[ed] in late 90s. It's unthinkable such a thing can happen today in any gay bar or disco.
"Contramano" marked a before & after in B.A.'s gay life. It's now an icon with mostly mature crowd (and its lovers). The owner has just died and I don't know if it's going to survive. Gay life has evolved tremendously since the 80s.
Hope this will help you to put your story straight.
