Isn't that obvious? A ban on headscarves does not solve a single problem of doubtful attitudes in families towards girls sexuality. It just caters for the needs of authoritarian natives who feel uneasy with all these immigrants.

"they can do what they like at home, but not in public." Indeed. And authoritarian parents will take care that their daughters stay at home as much as they can enforce. It is a problem for me because it is a problem for vulnerable girls.
