Having read
$1, a few things happened that quickly soured the conversation:
* You asked something that gets posted frequently between here, r/askreddit and other similar subreddits. It got bad enough over on r/askreddit that there's an AutoModerator string just to remind people that blind people can use computers and a direct link to our FAQ. When r/blind has to put up multiple pinned posts just to address how VI/blind people use Reddit and the proper way to harvest uncredited research data (and doesn't get read by people who can allegedly read more easily than us (add a lol here if you think it helps)), it's understandable why people here can get frustrated when yet another person asks the same thing yet again. It's like driving a bus and having a different kid ask "Are we there yet?" every quarter-mile and then they get confused when the driver gets angry. Sure, "they" only asked once and most of them can readily see out their window, but they did it anyway.
* It was phrased in the third person "How do blind people \_\_\_\_" as opposed to the typical second person "How do you \_\_\_". That often leads into the assumption that VI/blind people are incapable of answering for themselves and can only rely on third parties to act on their behalf (refer to bullet one). This is another stereotype that frequently comes up when people ask vision-related questions, which means more time has to be set aside to address it "again" before the actual question. It doesn't help that many users use such lead-ins for trolling or poorly-informed jokes, which often gets moderated as Spam or Harassment.
* " Of course those who are currently blind cant really answer" covers both points one and two. There was a link that led to the subreddit that gave the information you were looking for. Most of your replies from that point felt increasingly confrontational. It was less r/askreddit and more r/AmItheAsshole. By then, things broke down "again".
If you reached this point without skipping, I hope this helped you out. If you're looking for a TL;DR - started a conversation on bad assumptions, doubled down when provided info to the contrary, convo broke down. Not the first time, probably not the last. I'm sorry to hear things didn't go well, but I hope you find this useful for the future.
P.S. Personally, I like listening to podcasts, tabletop gaming (online because of COVID), and "watching" movies with descriptive audio tracks. I have some experience with video games but not nearly as much as I did when I was younger.
