Hi, Kazemon - first, welcome to the forums. You are certainly entitled to your opinions and are free to state them, and no one is stopping you from that. I don't know what your friend's username is so I don't remember the situation, but there are several fans of other pairings, KuroTomo included, on this board and they are always free to post what they feel about them, but you have to remember that other fans are free to post about their own pairings as well. As you said, having different opinions makes things interesting. I'm sorry if your friend was offended, and as I said, I don't know the situation, but I should hope that having lots of fans that speak out about their ideas and opinions doesn't discourage him from posting here, and everyone on these forums are normally very civil and get along well.
Before this turns into a debate that fills up the thread, let me point out that this discussion doesn't belong here as it isn't directly related to the current chapter. So if you could, a more relevant thread, like one of the pairing threads in the Manga or General Discussion forums, would be a better place for it.
Back to the chapter, I added the link to the chapter scans to the first post now so they're easy to find.
