Someone briefly posted this subject and then it disappeared. I would like to answer it though. I'm sure some will have opposing views and I welcome any.
Accepting someone who is Jewish but homosexual is like accepting someone who is Jewish but non-observant. While exceptions do exist, most orthodox congregations will accept them with open arms, will count them towards the minyan and will even give them Aliyas. It does not mean that the orthodox approve of it, but it does acknowledge that a Jew is a Jew. A Chabad tzadik once said that everyone in the minyan is 100% kosher when they come to pray.
This doesn't mean that the orthodox are going to change their ways and bend backwards to accommodate the political agenda of queers, but they are going to do what they can to bring as many Jews as possible back to the torah.
It is a common practice in Judaism to put a fence around the torah to make sure that everything is followed properly. The intention of this fence is not to keep others out but to keep the devoted close to the torah. If someone wants to ensure that they have a minyan of at least 10 shomar shabbat Jews I fully understand that they do their best to find one but at the same time it is better to have the minyan than to intentionally not have one.
Despite the orthodox being strict, they are usually more accepting than the conservative and deformed. While the conservative and deformed will kick people out for not paying dues, more than 9 times out of 10, the Orthodox will encourage Jews to come in rather than to leave.
In some cases a little torah education and knowledge is enough for someone to see the errs of their ways and become a better person.
