First off, the abaya is not a burka. It’s a fairly standard clothing item. The idea that an abaya in itself is harmful is absurd.
The harm comes from limiting the freedom of self expression. And that’s what France is doing now. Most Muslim girls in the west are fairly progressive, they don’t feel that they’re being forced to wear what they wear. So what happens then when the government actually infringes on their self expression? It’s not gonna make them look kindly on the institutions that will teach them western values, they will gravitate more to the institutions that will teach them Muslim values.
If you want rid people of their conservative ideals, you do that through education. If you try to force people to conform, you’ll get blowback and people only get more radical.
I don’t think they did, at least not the extent of it. It was a massive embarrassment to Netanyahu. 86% of jewish Israelis blame him for the attacks and more than half are asking him to resign.
