For the SG to deal (as they should) with the mounting drugs problem would be really hard. It would take money - for treatment centres, support, education outreach. And time. The results - if the programme succeeded - probably wouldn’t show up quickly enough to give them an electoral advantage.
Whereas gender reform, from SG’s point of view, is quick and easy (you just put words on a page to change the law) and the results will show up quickly.
Which is why SG like the idea.
Of course, the results in fact will be women and girls losing privacy, dignity and safety. What will show up will be men, when we’re trying to get changed. This might have electoral consequences....
