I only deconverted less than a year ago and I was much more "involved" in my faith than simply calling myself Christian. I was involved in youth groups, Bible studies, retreats, and went to a Christian college. For most of my life, the vast majority of my friends have been Christian, and usually on the conservative side.
I began coming out of the closet in high-school, and finished about half-way through college. All of my friends stuck by me, and I made plenty (for me) new ones when I was "out." Many of them believe that homosexuality is wrong. But we were and are friends, with varying political and theological beliefs, very different hobbies and study habits, beliefs concerning family and everything else, and differing opinions of sexuality. The friendships work because we recognize that we do not agree on some things (on a lot of things, in some cases), and we can work with that.
The word "homophobia" is overused by some gay people, and supporters.
The accusation that "homophobia" is being misused is also overused. A lot of people who are hateful towards homosexuals hide behind "Well, they shriek that at everybody" to disguise the fact that it is applicable in their case.
