I think it is very important to have a qualified monastic sangha in the West. Most of the Western monks and nuns whom I met were really sweet people, though I must say that all of them have gone through serious long-time meditation training. So I have no experience with people who were ordained just recently or just a few years ago. But truth to be said most of these monks whom I have met are not monks anymore (some of them after 20 years of being ordained). It seems to me that it is difficult for Westerners to stay ordained - this seems to be especially case with men. Though I only have experience with Tibetan monastic tradition, so I don´t know how it is in Chinese or Korean Mahayana monasticis sangha or in Theravada.
I think it is crucial to have a good and sincere monastic sangha of monks and nuns here in the West, because such sangha is an example of discipline for lay people and is a source of merit. Both of these are needed in order to progress on the path. I hope one day there will be such sangha, but so far it seems that there are only a handful people who are good monks here in Europe and most of them stay in long-time retreat, so it is easier for them to be monks as for their colleagues who are out in the open and have to travel and to deal with all sorts of people including attractive women.
I remember one funny scene showing how lay followers also need an education about monastic rules on their part. One very nice Khenpo visited a town were I used to live, not only is he learned, but he is also very relaxed and warm person. Immediately local sangha girls were trying to get all over him
Of course Khenpo being monk had to suffer this uninformed assault of these ladies and I later saw him sitting alone and reciting Vajrasattva.
