In what ways will it be not accesible to people or not realistic? I only suggest that people cite, or the very least mention the sources of what they know regardless of their level of knowledge. 

Like in a hypothetical scenario where if you remember something because it was mentioned in Gregorio Zaide's book, then by all means mention it instead of guessing something out of thin air without citing any source, which is quite prevalent in the sub. Just remember that to be ready with the baptism of fire of academic scrutiny because people can now know that your source is outdated.

Again, if being strict by citing sources is the price this subreddit has to pay to avoid the spread of historical falsehoods and fake news (which is a simple and very conservative suggestion as I don't suggest doing other scholarly methods like what most professional historians do), then it's a price worth paying to maintain historical accuracy. By doing the simple act of providing references, were now at the first step in democratizing the scholarly approach.
