If one desires to change back

Igros Moshe Orach Chaim 4:24

“Behold it is known that all the people of Poland, Hungary, and Russia…are children of Ashkenaz even Chasidim. And until Chasidus spread they all prayed with nusach Ashkenaz. However, the Chasidic leaders lead them to pray in a different nusach with various changes…They changed the customs of their ancestors and our great rabbis of Germany and France. The reason for the change is not clear nor how they permitted a change from the established nusach….If one desires to change back and pray in nusach Ashkenaz, since it is the nusach of our ancestors and rabbis, he is permitted as he is returning to what once was."

The glorious frum community of Germany

"HaKodesh Baruch saw we had passed the test of oppression. Despite all the tzaras, despite all the hatred, all the oppression, we remained loyal. There were a few Jews, meshumadim who sold their souls in order to get glory among the gentiles. There were a few. There were so few that they are insignificant. But Klal Yisroel passed the test. Now Hakodesh Baruch Hu said, I see you passed that test [of persecution in Medieval times]. I'm going to try you with another test now. [The test of emancipation in modern times.] Let's see how you work out this test. Now, when I said it was a calamity, it doesn't mean that the test was a waste, no. It was a minority that passed this test too. And those that remained loyal, they were a glorious example of the Am HaKodesh. Those that remain to this day. Many went lost, yes it's true. But an example, in Germany where there was so much assimilation, a number of German Jews decided they are going to fight for the preservation of the Torah. And they built up an Orthodox kehilla that was excellent in every detail. They were machmir in everything. In some respects, they were more frum than the Jews in Russia and Poland were. And they had organized kashrus. Strict hashgacha. Not rabbanim who gave heksherim and were paid for it. No. The kehillias gave hashgacha and were very strict in every detail. And so the minority that withstood the test were a glorious fulfillment of the prophecy that the Am Yisroel will continue forever despite any circumstances." 

Rav Avigdor Miller, Recording #855 - "The Kiss of Esav," 11:48

Definitely not a theocracy

As many chilonim in their hysteria continue to rant that Israel is heading toward a theocracy, the Nazareth District Court last Sunday barred the municipality of Afula from holding a gender-segregated musical performance at a public park. The city holds something like 360 events a year. And the Orthodox Jewish community wanted to hold just one event and to set it up so men and women would be separate - you know, according to the halacha. But the court overruled them on the grounds that such was a violation of principles of equality. Some theocracy.

We see that left-wing talk about respect for all cultures only applies to liberal/decadent culture. We see that the charedim in Israel are not a powerful group and need the support of Jews worldwide.
