Actually if you have to get rid of a Quarn you burn it because if you throw it in the trash that's disrespectful to the word of God.

You can also soak the pages in water to get the word of God off of it.

I don't really see a problem with someone burning a Quarn considering that's how you're supposed to get rid of them.

Is he spitting on it and putting it on the ground and being disrespectful like that?

Seems like he just wants to burn it. That's how you get rid of a Quarn anyway. So I really don't see a problem with this.

He could be more insulting about it but just burning it, I don't really see the big deal there.

But I'm Jewish so maybe I have no room to talk here.
