PCE (Partido Comunista de España) is not latino, is Spanish. Spain is part of Europe, not America.
That pic is from 1936, the year that the Spanish Civil War started after a failed coup perpetrated by Franco and the fascists, backed by Hitler and Mussolini. After the fascists won the war, we experienced 40 years of dictatorship.
One of the main political parties, Partido Popular (PP) was founded by former dictatorship politicians. In the last elections (past week) it was the party with more votes, but it isn't enough for them to form a government (they're trying to form a government with VOX, a extreme-right party).
Franco's dictatorship "ended" in 1975, so is really recent. My parents fought against the dictatorship when they were young and some of their friends went to jail for being communists.
If PP and VOX make it to the central government we're going back to that time. They already rule over some towns and regions and they're banning LGTB flags, women right organizations and everything that they deem as progressive.
