Yes, I haven't seen the exact posts you mentioned, But I do have to say that I have seen a few times where people are posting to people that have Legitimate Problems, and they don't seem to have anything nice to say, and end up saying something rude, that would have been better unsaid. I recently posted for advice on a personal problem I had, and although it did not pertain to chickens, I knew I would get some good advice from my wonderful BYC family (And I did, Mostly, Thanks Guys), and I actually had someone post "Get Over It" to me, and in the same post attack another person who posted, in a very rude manner, pretty much brushing off that they had real hopes and dreams and saying that were not important. They may not have been important to them, but to the person with those dreams, they were extremely important, and they should feel comfortable posting, and knowing they would get productive advice. In that thread there actually were quite a few people who PM'd me over the person saying "Get over it" they could not believe they said that, But I got a lot of good advice, so over all I am happy I posted.
Please just read what you are posting before you submit it, I do, and have actually decided not to post what I wrote, as it wasn't my place.
