It’s forbidden to start a fire on the Sabbath. It’s also forbidden to extinguish one,from what I read,but only the fanatics would allow a fire to burn without putting it out. I don’t understand that at all. I don’t think G-d would want people to lose their homes or businesses.
There were some Ultra-Orthodox Jews who smeared vomit on the door and windows of a bakery that sold Chametz,or anything with leavening,during Passover.
Then there are those who throw chairs and dirty diapers at the women who are praying at the Wall in Jerusalem.
I am appalled at those who spit at/on Christians or Christian religious objects,such as a crucifix. That is not part of Judaism. I still have several sets of rosary beads from when I was a Christian. A Catholic woman gave me two sets and my mother brought back some really nice ones from Italy. I have them in a safe place.
I don’t understand some of the practices,either. there are those who adhere to everything a rabbi says but I prefer to go according to what’s in our Scriptures,not someone’s translation.
Every group has it’s kooks. The examples you gave must be of people breaking the law? Do they get arrested for assault? Is it legal for women to go to the wall?
When people say things I don’t like or agree with in the name of God, I usually just ignore them. I know they don’t influence God. LOL People can yap all they want. But violence against others...that would be a self defence gun thing America.
