While westerners always argue that Muslim women who cover up are deprived from human rights and not treated equally, but many muslim women don't think so. Muslim women are willing, happy and proud to wear the hijab.
Anyway, ask men to wear to veil is a good suggestion to let them experience the feeling of cover up. It is not an Islam teaching to ask men to be covered up, but it is good for men to experience someting they like but never try before. Women can do it, there is no reason why men cannot do it.
