Fair enough, I can see your point. But it also gets back to the point of the respect thread. It's not the informed poster's duty, in a given thread, to show everything to get others on the same page. If you're interested enough, you should be able to take some time to learn about the characters. There is an element of effort involved. Because, why did I make the Authority thread if not to avoid explaining myself every time I talk about them? I did that back in the day. It sucked balls.
If a feat is in question, sure. Otherwise, if I say something like "the Doctor froze Majestic with a thought" or "he can time travel and exist in the sun" they're just feats devoid of interpretation. They don't require the same level of justification imo.
