Religion/culture are used all too often to excuse behaviours and to ensure that they are never criticised.
The same behaviours wouldn’t be accepted outside of those religions/cultures so why does religion/culture make it ok? It doesn’t. And the sooner this becomes a mainstream view the better.
By way of an example, parent takes a tiny baby into a shop to have its ears pierced. They hold it down and listen to it scream while they do so, and people judge, until someone says “but that’s what they do in x culture.” At which point the judgement is expected to cease. Why should it? It’s no less child abuse if it’s cultural than if it isn’t.
It’s the same with this topic. If a white atheist but sexist misogynist man started demanding that his daughter cover up not a single person would defend that. Yet a knowingly sexist misogynist religion insists that girls cover up,and those who judge are called islamophobic. IMO there’s no such thing.
Islam as any religion is a choice, and while I absolutely defend anyone’s right to choose to live however they want, that does not absolve them of criticism for the choices they make, especially on behalf of their children.
If you come from any religion, then you have to accept that if you choose to be part of that religion, people will associate you with its negative traits.
And as much as people are criticising the OP here, we all know that unfortunately plenty of young girls have been indoctrinated into Islam. The same young girls who have often ended up in Syria. And plenty of boys are indoctrinated into Islam, they end up as the pawns of terrorists.
Most Muslims are of course not like that. But a Muslim woman who wasn’t like that would know what kind of impression it would create if she started encouraging her stepdaughter to wear the hijab. It’s indisputable.
