There are justifications for anonymity and 2chan and 4chan originally stated that was their goal, that you should be judged by the contents and not by who you are. But as 4chan has shown when most people are anonymous, they default to trolling and junk posting. Theres no real reason to ever think out your arguments or locate facts because there are zero consequences for you if you're wrong and even if you thoroughly dismantle someone else's argument they can simply start posting somewhere else with the same nonsense because people can't just go back and look at their history and copy and paste the replies to their junk arguments. When someone has a reputation of any kind to protect they tend to try to reply somewhat intelligently. This site makes it pretty easy to create accounts for when you need to be anonymous, but in the vast majority of cases you don't need to be. This community self-moderates pretty well so even someone with a high reputation can be replied to with a well thought out counter argument and not be downvoted simply for disagreeing
