Discussing anything of substance on a social media is a bad idea. These sites incentivise short arguments. Twitter very forcefully. Facebook implicitly with its "See more" links, for when comments get long.

But it's also a result of the reactionary culture of those sites. People want to be offended. They think that because the comment is on the internet, that it's final, and intended as is. But it rarely is.
