This comes across a bit snobbish or elitist really. It sounds like you are dismissing anyone's opinion unless they are as experienced and talented as yourself.
I've seen something similar to this with professional photographers who can't cope with the mass of amateurs present on the Internet, and the phenomenon of sites like Flickr. Some attitudes are that unless they are professional, they should not be posting their photos and anything they post or any opinion they have is irrelevant, and their photos are rubbish even if they are as talented as some of the professionals. Understandable attitude given the devaluation of the stock photo market, but it's one of not adapting to the changes in the market and technology. I'd rather see professionals move on, embrace the amateur, and find other business opportunities.
As far as critique goes, everyone's opinion is valid. If you don't want critique, don't post the photo. Perhaps a dedicated professional or "experienced" forum is better for you though if you don't want the plebs commenting
Personally I value anyone's comments, whether I agree with them or not. Those from people less experienced than myself are often interesting because they may see things in a photo in a different way to an expert. Now I'm absolutely no expert, I'm clearly one of the inexperienced, not skilled or talented, but if I was more of a professional and maybe wanted to exhibit my photos professionally, I'd want everyone to be able to enjoy them and I'd be interested what the normal members of the public would likely see in them as they're a key part of the audience.
Now, okay there's the situation of someone less experienced spouting technical facts that they may be clearly ignorant of as if they're experience. I'm sure you'll find I'm such a person!

. But why not take the chance to offer some polite correction if you know better? They have to learn somehow.
p.s. dismiss as you like. I'm one of the inexperienced and low post count too if that kind of thing bothers you
