This may be indicative. Surely you guys have heard Thai girls say they are frightened of getting in a Bangkok taxi alone? They also do not like to live in an apartment building with lots of Thai men. They don't like living in a neighbourhood with "lots of Thai men" who hang out in the pool halls, karaokes and soi-side drinking places. They most certainly don't like going into clubs or restaurants alone.

In summary, there's a great mistrust of Thai men, according to many Thai ladies I've talked to. So there must be reasons. Those reasons include being robbed, physically assaulted, raped, etc. I don't think this is anything new, it's just that some authorities are actually trying to provide a morsel of safety. Could be military inspired. I don't know.
