Queer has absolutely been used as a slur that contributed to the repression of several people I know personally, for one.

For two, "it's unwieldy" isn't really a good enough reason to shortcut on representation - the reason LGBT caught on is because it started as LGBT, and the QIA+ was added as it became apparent there were people who should be together under the umbrella but weren't represented. It's also simply not unwieldy in the context of a game tag - the full tag will come up when you type LGBT while adding a tag, and it will be a suggested tag if you search LGBT. I don't know how the itch search actually works but I wouldn't be surprised if just searching for LGBT also matched the LGBTQIA+ tag. So it really isn't unwieldy in this context, and the more it's used in common situations like this, the less "unwieldy" it'll be in normal conversation - it'll just be "correct"

I indeed read the entire thread before responding - that's why I'm aware that not all contributing voices are on board with your suggestion. However, even if I were the only voice in disagreement, I would still make my argument. This is what I believe, and as an LGBT game dev I have a stake in the outcome of the debate. Let's try not to marginalise dissent with appeals to majoritarianism - it rarely leads to a just outcome, and it is an odd position for anyone attempting to represent minorities to take.

Further to that, I made absolutely no assumption for the community as a whole in my reply - I simply represented my own views on the matter, and pointed out that not everyone in the community is coming from the same place. Ironically, your last post makes a number of assertions representing yourself as the voice of the community - which I don't accept.

Returning to the meat of your argument, many folks would also not feel included in LGBTQIA - rendering it an inefficient solution to the problem of inclusion. Another thread would simply start up requesting LGBTQIA2S - then LGBTTQIA2SA - ad infinitum... If all these tags are to become visible searches, they will end up clogging the search system and leading to players missing out on content they might otherwise enjoy. Since each game is only  allowed 10 tags, creators would also be in a bind - they surely won't wish to make all 10 tags variations on the LGBT+ theme, but they won't want to be missed out on each of the individual searches.

LBGT - as the most generally recognised umbrella term - seems to be entirely adequate for the search and tag functions (which are, after about functionality and ease-of-access rather than addressing any questions of inclusion and community). I am, however, somewhat more supportive of a separate Queer tag - owing to its combination of sexual and political orientations.
