I hate threads on this subject. It's so hard to express an opinion that phrased in the right way to avoid being offensive.
I am sympathetic to the view that telling women that they shouldn't wear something is not really that different from telling them that they should. It can also be dismissive to assume that people who do wear these items are poor, downtrodden victims.
However, any difference in appearance that is based on anything other than biology, always makes me suspicious. How come men don't wear modest clothing that is as restrictive as a burqa, or high heels and makeup for that matter?
Striking the right balance between personal choice and true liberty is tricky. The best way is not to have rules about it but to try to create a world where education allows women the freedom to make a true choice (rather than a culturally dominated one).
