I agree,their exclusion of gay users is certainly an issue that would be nice for them to fix. To play the devils advocate,they do use a rather complex matching system using a personality test. Adding gay users is not as simple as just allowing the database to query same sex matches. They make a lot of claims that about their "Scientific matching" and if we take them at their word,that there was some testing to make sure that this system actually works,it would be a significant cost to test to see if their model works for same sex matches and if not to develop a new one. If the answer were as simple as just changing a few lines of SQL code I would say there is no justifiable reason for their site to discriminate but if it costs a signifigant amount of money,then I understand why they might choose to serve one narrow segment of society. I think however this is not the case. It turns out that e-harmony, to settle a lawsuit, made a separate gay dating site (compatiblepartners.net). This is a significant cash outlay in maintenance and development. It would seem that it would be much easier to setup a new front end to the e-harmony database and let a few thousand gay people do a free beta test to prove or disprove the validity of their model for same sex couples,which presumably is similar to the way that the side was presumably created for mixed sex couples. If it works,there is no reason not to allow same sex couples. If not,then they can reasonably explain to anyone who complains that the system simply does not work for same sex couples. In fact,they could even allow it to match same sex couples,with giant red warnings that tell you that the personality matching just will not work,and your throwing your money away. If you want to flush your cash down the toilet,go for it. The fact that they decided to spend all the money on a different site suggests to me that the model may well work for gay couples,and that they just want to exclude them from the eharmony site. Im not sure if it has similar matching,but that would be even more evidence that they want to discriminate. (Keeping their e-Harmony brand "gay free" certainly seems sort of sleazy to me)
