Excepting of course that just as you and many here do, you assume your opinion in the group of having higher value. Yes it is easy to pick out the obvious bad opinions but it becomes far less easy to do so when the issues are divisive because both sides can be correct but you can guarantee both sides can have proponents who think the other one is an idiot.

Reddit's issue for me is that many supposedly good subs are so completely toxic to any opposing view they may as well not exist.
