Even if you want to “entitle everyone to their own opinion” (which is often questionable), why does a chareidi website not espouse the daas Torah outlook? For the record, the opinion of the Gedolei Torah is that we don’t have to “be thankful” to reshoim even for something “good” that they might have done. Generally, the evil and destruction they have perpetrated outweighs anything good they might have done. The Brisker Rav told people that saying the truth (about what the reshoim are doing in E.Y.) is permitted and doesn’t constitute “dibas ha’aretz.” And 147, what exactly changed “overnight” on the 5th of Iyar? Zero changed on that day, except (according to the words of the Chazon Ish reported by some) “the day Hordus (Herod) seized control of the country.” You are commemorating the outbreak of a war that has not ended to this day. It would make more sense to celebrate the day they signed an armistice with the Arab states in 1949. But 5th of Iyar? And before you sing the praises of the reshoim whom you think provided a “safe haven” for the wretched Jews of Europe, don’t forget that “one cow in Palestine (E.Y) was (considered) worth more than all the Jews of Europe.” Jews got into E.Y. despite the zionists, not because of them.
Regarding the weather, the Chafetz Chaim brings a statement from the Ben Ish Chai who says one shouldn’t criticize the weather in E.Y. and that this could be a form of “dibas ha’aretz.”
