I have to agree with Pork Store. There have been many references to Phil and a gay background. Most have been mentioned above. In addition there is the presence of his wife who is homophobe, church doctrine quoting, all of this to him all of the time. He probably cannot stand her, hence the affair right in her face, with their housekeeper. But she is his wife and he has her coming down on gays constantly, while he has probably been in the position that she detests. She gives him no way out other than to rain down her hate on Vito and others.
