i don't think it is. As a christian i know it is seemed to be a very unholy thing to do because God created man and women to go unite. Not for men to unite with men and the same for women. This is concidered to be the work of the devel and is there for frowned apon.
However, as a personal opinion, i think that people have the right to do what ever they choose to do. No one can really tell them otherwise. We all have rights to live the way we won't. Though as a straight person really i can't really see the attraction to fall in love with someone of the same sex so for me it is a little weird but i have nothing against it.
