My [41F] husband [43M] kicked our son [17M] out of the house!

This is not a sick or malicious joke. I'm posting this because I'm not sure where else to turn, and my family is being torn apart. I could really use some help and guidance on where I can turn for help.My husband and I have been married for 14 years. When I married him, I knew that he was not too fond of homosexuals and was homophobic, as his father was. I was raised to be more open-minded and believe that we are all equal. I continue to be an open and accepting individual.Our son is 17. On New Year's Day, our son came out as gay to my husband and I. I always had an inkling that he was gay, but regardless he was still my son and I would love him unconditionally.My husband became quite vulgar and disgusted when our son told us, despite our son breaking down into tears. It broke my heart that my husband had created a hostile environment to the point where my son didn't feel comfortable confiding in his own parents.My husband did not say a word when my son had finished explaining, but instead he left the room, and came back with a duffel bag, which he began filling with my son's clothes. Under his breath spewed words of hate and derogatory statements that caused my son to feel very uncomfortable and scared. My husband proceeded to tell my son that he was not welcomed in my home, and that unless he was cured of his disease, he could not return back into our home. My husband dragged my son and literally threw him out of the door without so much as a goodbye, but with only his duffel bag of clothing.While this had gone on, I pleaded to my husband to understand, but he threatened that he would leave, saying that I had to "choose" between my son and my husband. I chose my husband, but only because we have two other children who are young and require a father. I felt terrible, but I thought that my husband would get over it, and I knew that my son had friends he could stay with, and that I could contact him on his cell-phone to tell him it was okay, and to comfort him.My husband has ousted my son out of our lives.I don’t know what to do. Was what my husband did justifiable enough that I should support the incident? If I tell the police, I fear that he will never come back, and give up custody all together. My husband genuinely believes that our son has a disease, and he no longer cares for him. My husband believes that having his “gay germs” in our home will spread to our younger children, who are twin boys aged seven, and he believes that others will think differently of him now that his son is homosexual.I feel terrible.Please help me. What do I do? Is there some sort of organization or support group that can assist our family?tl;dr: My son came out as gay to my husband and I on New Year's Day. My husband didn't take it well. He threw our son out. I tried to convince my husband to understand. He told me I had to choose between him and our son. I chose him only because we have two younger children, who need a father. I know my son is currently living with friends and is safe. However, I feel really badly and I need some advice. via /r/Parenting http://bit.ly/2QlDQql
