Opinions will differ between individuals but as a generalisation, followers of any path under the Pagan religion tend to be more accepting and less bigoted than followers of mainstream religions. Certainly my own views on homosexuality are very positive. I believe everybody has the right to express their sexuality in a manner that feels natural to them. Unlike followers of some other religions, I do not believe that the God or the Goddess would view homosexuality as a less acceptable sexual orientation than heterosexuality. The same would go for transgender, transsexual or transneutral individuals. To me, a person who finds and walks their own path is true to themselves. A person true to themselves is to be respected.
There are gay Wiccan/non Wiccan covens throughout the world who practise their faith in the secure environment of others who share their sexuality. These can provide positive interaction for witches who prefer to practise their faith with others of a similar orientation. However, as most witches tend to be open minded as to all aspects of sexuality, most covens will have members of diverse sexualities.
Also - why limit your fun to only 50% of the population? That's this witch's view!!
