In August 2015, a number of conservative and right-wing public figures and Catholic clergy members (including most notably Sisak bishop Vlado Košić and auxiliary bishop of Zagreb Valentin Pozaić) signed a petition and an open letter to the President of Croatia Grabar-Kitarović and to the chairman of Croatian Democratic Union Tomislav Karamarko, calling for the introduction of the salute as the official salute of the Republic of Croatia Armed Forces. In June 2016 Elvis Duspara, a Catholic blogger and columnist, published a book titled "Za dom spremni" in Zagreb, focusing on whitewashing the salute and claiming that "this salute is in the DNA of every Croat." Croatian mathematician and academic, controversial far-right writer Josip Pečarić, published a similar book titled "Diary Under the Sign of "Za Dom Spremni"". Its presentation on public premises was rejected by Tisno local authorities.
