Yes.
Harav Shmuel Auerbach and a group of Rabbonim have given the directive to demonstrate as they believe this is a crucial matter. The people who only listen to them are making a Kiddush Hashem.
About blocking streets and Gezel Zman etc. Did you have the same concerns when the Belzer Chasuna or Gerrer Chasuna blocked the whole Yerushalayim ? What about Hachnosas sefer Torah which blocks streets? What about when Harav Shteinman said to protest three years ago and a half. A million people blocked Yerushalayim for a whole day ?
When it’s not your veiw it’s a Chilul Hashem and when it is your understanding it’s a Kiddush Hashem?
While Harav Auerbach and his Roshei Yeshivos are in minority they can still decide what in their veiw is something worth protesting about.
