Hurr durr
I'm not really avoiding spoilers. I just feel that if people are free to post whatever they want we can have more discussions. For example one creates a thread entitled "Who's the best Clannad heroine", to avoid spoilers people will probably post something like "I like heroine X. So cute" or something. If one can post without caring about spoilers, one can answer "I like heroine X because in her route this is blah blah bullshit compared ho heroine Y where shit is blah blah blah".
Even you said that you want to discuss something about Rewrite but cannot because you might be able to post spoilers
