CMV: US-defaultism is not wrong in English language subbredits that are geographically undefined

The term "default" originally referred to a legal or financial failure. Over time, it also came to refer to what happens when you fail, which further refined into the broader concept, not limited to legal and financial contexts of what happens if you don't specify or make a selection.

In other words, sometimes we act based on information. If that information is not specified otherwise, we must make an assumption. This is the process of defaulting as it is used in the social /US-defaultism context.

How reasonable or unreasonable is US defaultism?

≈43% of Reddit's active users are American, about as much as the the next 23 countries on the list combined, with the next highest coming in at <6% (UK). I have not been able to locate a reliable source telling me how many users speak no English at all.

≈43% is the overwhelming plurality of reddit users.

If you were to pick a reddit user at Random and ask if they are from India, your odds are about 1-in-20. If you were to ask a random user if they are from the UK, your odds are about 1-in-20. If you were to ask if someone is from Canada, your odds are about 1-in-20. If yoh were to ask a random redditor if they are from America, your odds are about 9-in-20. You can just about flip a coin on any given Reddit user on whether they are American or not.

Furthermore If at least ≈14% of users do not speak any English at all, this means that 14% of Reddit users do not interact with English language subs, and Americans make up the simple majority of English-language Reddit users.

If not, America is still the overwhelming majority of users with English as a first language. This is not disputable based on the numbers, and is, in section circumstances times, the more relevant measure for a given discussion on US-defaultism with regard to language.

Okay, but why have any assumptions / defaults at all?

Because assumptions are massive time-savers. If someone posts a question in English and doesn't say what their culture is, you can (a) answer from your own perspective, (b) make an assumption about where the person is from, or (c) answer with an exhaustive list that answers the question based on every possible culture. The only difference between Americans and the rest of you is that we're used to bundling options (a) and (b).
