You would need to scrape it using a personal API key which does have rate limits theoretically?
That would be the most efficient way. You’d need to both write to a database and a document storage for the photos/videos.
Otherwise you could scrape it through a browser using a library like puppeteer and store it similarly. But that’s probably the worst way to do it considering the API for reddit doesn’t charge yet. It’s really looking for title, (content, link, image or video), and OP. Comments are likely a waste of time to grab in most instances and would be hard to integrate back to Lemmy in its current state.
I’m a gay cis-man with a trans sister and we’re lucky my parents, grandparents, aunts and uncles are all supportive. My grandma has even corrected herself misgendering my sister by accident. My husband also has a gay sister who has been married for 15+ years. There are families out there that are accepting and filled with queer people!
