How are they “evil”? Perhaps you can say they are not flawless in their observance of mitzvot. Okay, but no person, no matter how chashuv, is innocent of that. They are not harming anyone. They want to observe Rosh Chodesh at the Kotel, the site beloved to all Jews, which by the way was built well before such distinctions as “Orthodox” existed in the world.
I remember reading a frum children’s book when I was young with a mashal. I am sorry that I cannot remember the title or author, but I think it was published by ArtScroll or Feldheim. The mashal described a young boy who went to shul with his father on Yom Kippur. As the chazzan davened, he sensed that the prayers of the kehilla were not being accepted by Hashem. He continued to daven with kavanah, tears streaming down his face as the day wore on and nothing changed. Meanwhile, the little boy did not know how to daven and could not even read the Alef Bais. He stared down at the machzor, unable to daven with the kehillah although he desperately wanted to, and eventually when he couldn’t stand it anymore he took a small wooden whistle out of his pocket and blew it. Everyone turned around to stare at him and his father turned bright red and began to chastise him. The chazzan, however, silenced the boy’s father and explained to the kehillah that all day, he had sensed an obstacle and that only the boy’s simple whistle had been able to open the gates of shamayim to the pleas of the kehillah. Yes, the boy in his ignorance had violated a Torah prohibition, but only he had sufficient kavanah and desire for closeness to Hashem to elevate the entire kehillah.
