Part of being a Charaidi in Israel is expressing yourself in extremes. If pushed, the Rosh Yeshiva would tell you that in his heart, he is saying this as a Guzma.
Unfortunately, this is part of living in a community that has the motto Semper Timere Extranei, instead of Semper Sursum or (my favorite) Semper Fidelis. Without extreme statements, the Rosh Yeshiva would be marginalized.
