Leia, Fizz's silver testing comment was in reference to the OP basicly stating (or implying) that because each and every one of the foals she produced carried silver, then she was going to pass it to all. They said they knew for certain the foal in question carried silver because the dam produced all silver foals.
Also, minifrieshorsefarm was absolutely correct. I don't consider her making a correction to the accuracy of a statement to be "fussing" over a post. The person that posted that bay was red, when talking specifically about color and color testing posted misinformation and was good that it was corrected, as I am sure it had many readers going HUH and scratching their head. I remember years ago, in the Barbara Naviaux color article published in The World, she showed the smokey colored undercoat that silver can cause to a bay...thus, silver bay.
