As one of the 60+ upvoters I want to emphasize that this is not about having the right to misgender you. Like many others, I try to be as respectful as possible to people's wishes about their pronouns and I do think SE should be tougher when it comes to harassment and discrimination. But they can do that without forcing users to do something that goes against their personal beliefs: by having a guideline that says "don't intentionally misgender people". The difference between this and the new CoC is big for the free-speech people, but (I would hope) negligible for trans people.

Nice, I'm very glad to see this! Looking forward to a cool design!

Cool, a scientific investigation! :D But I'm not sure. For example, "Present tense or Future tense (When writing articles or technical guides)" to me is a perfect "grammar question" for Writing.SE. It's not really about grammar, because both cases are grammatically correct; it is about how grammar should be applied in this specific situation to make a good, readable document. In my opinion that question is more on-topic here than in English.SE.

Because we have English.SE for it. Just like worldbuilding questions are off-topic due to Worldbuilding.SE, despite actually being very important for writing. The saving grace of grammar questions that are universal is that they are not governed by English.SE.

It's fine to have style/formatting questions that are more relevant for specific languages than others, because style & formatting are purely about writing and there's no other SE for it. If you have a grammar question that's only relevant in English, you have to have a good argument as to why it isn't on English.SE. I can't imagine these questions that belong here instead of there while only being relevant in English. What I can imagine is a grammar tag that deals mostly with abstract questions about grammar as a writing tool, which would be relevant in all languages.

I didn't ask the question in order to find consensus for removing the tag, as I hope is clear from my original post. But I don't think you have engaged with my arguments. English grammar should not be a topic on this forum. The questions using the tag should be valid in all languages.

Oh, was that actually bad grammar? I was hoping it was just sloppy English. :D Thanks for the edit.

@curiousdannii, but that is also not the point here. We have a recent discussion about that tag here so maybe offer your improvements there. This question is about "word-choice".

Two different things, I'd say. Voice as "creating sounds" is very different from the rest and could be removed potentially. "Active/passive voice" would be its own thing of we're taking about grammar, but here it's included as part of choosing the right voice. For example scientific reports use passive voice frequently, so it's an important detail for copying that style.
