You're right and I apologize for not phasing that properly.
The good thing about the SYW areas is an author can request the level of critique they get (light, dark, extra-crispy), but at all times, critiques should be beneficial. People should be critiquing the work and they should be working with the author to help make improvements. That can be a full line-by-line with references and etc. at one end of the spectrum all the way to "I"m not sure why, but this isn't working for me" at the other. However, as AW Admin pointed out, respect your fellow writer is paramount, but also, don't immediately disregard a critique because someone didn't like a turn-of-phrase you particularly liked. Take some time, process what's been said, and then look at it one more time before responding. What seems annoying at first might just be the piece of critique you need to really polish your work.
On the other hand, it's all opinion, and to quote an old song, "You can take what you need and leave the rest".
I just tend to warn new(ish) authors that developing fire-proof rhino hide is a good thing because as soon as you release anything into the ether, someone out there isn't going to like it and boy, will they tell you about it.
