Sorry I haven't seen a thread about this yet and it is a very good article.

Hatred of lesbians is a result of patriarchal attitudes that demand subservience and capitulation to men. Lesbianism is a threat to bigoted misogynists who believe women need to be “kept in line,” either by a father or a husband. Lesbianism is an affront to these men, for the simple reason that we have refused compulsory heterosexuality and have openly and unashamedly rejected men sexually. Until we eradicate sexism, anti-lesbian violence will be all too common.
