If people want a respectful space to discuss among themselves I don't see any good reason to force myself into the conversation. Not every space on the internet (or real life) needs to be a stage for the free marketplace of ideas, especially when you're talking about already marginalised communities who are easily disenfranchised by many of the kinds of people attracted to that style of space.
Personally, looking at the interaction between yourself and the mod, it reads to me like you was the one who was sarcastic and rude.
I don't really think I can come up with a more concise way of summarizing the idea than anthropologist Audrey Smedley did on the first result of the Google search "race social construct"
Race is a culturally structured systematic definition of a way of looking at perceiving and interpreting reality.
I would recommend you read something like "Feminism and 'Race'" from Oxford Readings in Feminism or some of bell hooks' work to understand the idea better.
This feels more like two questions, so I'll answer them both:
If you're trying to learn programming and know at least some basics, my only advice is to pick a project you're even a little interested in and get started. Don't worry about operating system, it doesn't actually matter that much unless you're working on iOS or MacOS! A weather app for whatever language/platform you're working with is usually my first suggestion for students.
There are plenty of legitimate reasons for Google to provide extra support and exceptions to parts of their guidelines to certain parties, including themselves. No one is claiming this is a consequence-neutral decision, and it's right to not inherently trust these exceptions, but it is not a black and white issue.
In this case, placing extra barriers around sensitive permissions like MANAGE_EXTERNAL_STORAGE for untrusted parties is perfectly reasonable, but the process they implemented should be competent and appealable to a real support person. What Google should be criticized for (and "heavily fined" by the EU if that were to happen) is their inconsistent and often incorrect baseline review process, as well as their lack of any real support. They are essentially part of a duopoly and should thus be forced to act responsibly.
In my experience, an LLM can write small, basic scripts or equally small and isolated bits of logic. It can also do some basic boilerplate work and write nearly functional unit tests. Anything else and it's hopeless.
