Hmm, alright, a simple miscommunication over what the discussion was about; two sides were arguing over entirely different things without realizing it.
Anyway, I agree that it shouldn't be a big deal when it comes to sfw stuff (it objectively is a big deal, otherwise we wouldn't be having this conversation at all, but it shouldn't be). For nsfw stuff though, it is pretty important.
No idea whether what Jhaerik said above was actually homophobic or not; I can easily see it as another unfortunate misunderstanding. As I discovered earlier, there are at least 8 gay tags... and upon seeing that "yuri" was among them, I have checked and confirmed that there is a "yaoi" tag as well, bringing it up to at least 9. Even without any problem with LGBTQA people or games themselves, that level of redundancy seems a bit excessive... and when there certain noticeably missing tag options, seeing that redundancy concentrated all to one area can be a bit infuriating. Regardless of their motivations though, they did have a good idea about adding a Straight tag. Because again, in certain specific contexts it is important to specify that, and this site lacks (and more infuriatingly, refuses to build) the infrastructure necessary for us to not need to add it for filtering purposes.
