If you can't stand by your posts, you are mentally weak.
If you can't back up your posts, you have poor arguments.
If you are challenged and lose, you are weaker than I thought. What people really hate about IDs is having to live with the shame of losing an argument or debate for the thread. You do get judged silently, it is difficult to come back from that, it is embarrassing. That's why IDs encourage you to make good posts or if you make a controversial post, you better be strong enough to defend yourself without resorting to the usual "no u" and goalpost moving kiddy play anonymous users are used to. We all know shitposters are weak, god I wish I could eat one alive I hope it happens before 4chan comes back.
