Gender segregation against equality?

We've got some smart people working at the London School of Economics:

A top UK university has accepted that gender segregation that took place at a gala dinner, which saw women and men separated by a curtain, was unlawful, The Independent can reveal.

The London School of Economics (LSE) came under fire in March last year after the Islamic Society held a gala dinner for which students had to buy separate tickets depending on whether they were a “brother” or a “sister”.

When they arrived at the event, held at a banqueting hall in central London, there was a large screen separating the men’s tables from the women’s ones, stopping the attendees from even looking at each other.

At least this way the "brothers" don't rape their "sisters".
