據2001年人口普查顯示,波蘭裔立陶宛人有約80%以波蘭語為母語,9.5%以俄語為母語,7.3%以立陶宛語為母語[23]。部分波蘭媒體(英语:Mass media in Poland)與政治人物認為波蘭裔立陶宛人受到歧視,批評立陶宛拒絕在波蘭裔集中的地區設立立陶宛語與波蘭語的雙語路牌[24]。立陶宛憲法規定所有公民都需以立陶宛文書寫自己的名字,並使用立陶宛語發音,因此波蘭裔在正式文件中也需使用立陶宛化的姓名。2011年4月歐洲議會接受了一項關於波蘭裔立陶宛人語言權利的提案(0358/2011提案)[25],同年波蘭前總統萊赫·華勒沙也批評立陶宛政府對波蘭裔立陶宛人有差別待遇,並因此拒絕接受立陶宛頒授的维陶塔斯大帝勋章[26]。

The irredentist campaign tainted Lithuanian society with currents of hatred and revenge directed against the Poles. In fact, the largest social organization in interwar Lithuania was the League for the Liberation of Vilnius(英语:League for the Liberation of Vilnius) (Vilniaus Vadavimo Safunga, or WS), which trumpeted the irredentist line in its magazine "Our Vilnius" (Mūsų Vilnius).
