Yep of course there are a few who need to tone it down a little. But they are not usually having a personal go either. Just putting it bluntly and it gets taken in the wrong context. And once people have their back up over something then they continue to be under the impression that every comment that is not 'you are perfect' is a personal attack.
Nothing on this forum is a personal attack unless you know each other personally. We come from all corners of the globe, will never meet so don't take things so personally!! Does it matter if someone in South Africa thinks someone in Iceland has a terrible position?????
Take each and every critique and USE it. 99% of the people who respond to a critique are doing so to help you. They've put in the time and effort to type out a long response, and to have the OP turn around and have a shot at them saying they don't know what they're talking about is a huge kick in the guts when you've put effort in to help that person.
I know when I have posted a reply to some critique threads I've been shot down in flames by the OP, often I've spent over 30 mins typing out a reply to a critique, and will give a detailed explanation on the possible causes of the problem, and give what I can as a solution. Unfortunately, this picking things apart bit by bit appears to many posters as though I am having a go and pulling them apart.
This is entirely not the case. I comment on every detail of the picture that is put in front of me, because the horse works as a whole and you need to work on every problem to achieve the desired result of a supple, straight and engaged horse.
