During his 2011 election campaign Hirvisaari was critical of the immigration policies in Finland, and supported national sovereignty as well as Finland generally as a country. In July 2011 Hirvisaari stated that the killings in Oslo on 22 July 2011, by right-wing extremistAnders Behring Breivik, were a side-effect of Norway's immigration policies. Just before the 2011 general election Hirvisaari was prosecuted for his blog in the Uusi Suomi newspaper web site under the title "Kikkarapäälle kuonoon". The text referenced an attack on a foreign person in Helsinki — Hirvisaari wrote that the crime had not necessarily been a racist one. In November 2010 the district court of Päijät-Häme dropped the charges against him of incitement. After consultation with the deputy general attorney, Jorma Kalske, the state appealed against the verdict. In December the Kouvola court of appeals found Hirvisaari guilty of incitement and fined him. In October 2013, Speaker of the Parliament Eero Heinäluoma issued a notice of censure to Hirvisaari for an incident where he had invited far-right activist Seppo Lehto as his guest to the parliament. During his visit, Lehto made several Nazi salutes, including at least one instance where Hirvisaari took a photo of Lehto performing the Nazi salute from the spectator gallery overlooking the Parliament House's Session Hall. Photos and videos of Lehto performing the Nazi salute in the Parliament House were then distributed on Lehto's public Facebook page and on YouTube. The Finns Party leadership then unanimously decided to expel Hirvisaari from the party, citing multiple cases of acting against the party's interest. After his expulsion from the Finns Party Hirvisaari joined Change 2011, becoming that party's first MP. In the 2015 parliamentary elections Hirvisaari was a candidate for the Muutos 2011 party on the Uusimaa electoral district, but did not gather enough votes to be elected.
The board of the Finnish nationalist association Suomen Sisu congratulated Hirvisaari for his election to the Finnish parliament and referred to him as "one of its members". In 2013 Hirvisaari resigned his membership in Suomen Sisu, but he rejoined the organisation in 2014.
