I hypothesize that any "short reactions" like reaction buttons, shares and ~200 characters posts are used to express outrage and hate because it's the only emotions that can be accurately expressed with such limited way of expression. "Fuck you" has a lot more meaning and impact than a "thank you" without additional context; anger encourages short and impulsive actions, kindness necessitates understanding and sophisticated social interactions. "Thank you for helping me out when my wife threw me out of the apartment" has more punch than just "fuck you" but also requires more involvement to even produce the initial situation that began the chain of event. Researched arguments are nearly impossible to find compared to the sea of impulsive reactions. As an example of this is the difference between 4chan's /b/ and /r9k/ boards. /b/ is pure random, with nothing off limit except what is illegal under the law while /r9k/ is similar but no duplicates of text or picture are permitted across all the history of the board. While the post on /r9k/ remain vulgar, insults are far less prominent. Specialized groups/boards/subreddits are also similar where content and researched opinions are the main point of those groups by their nature.
