for the first, the comment was more directed to you, you had posted been responded to and did not pass on the information you had been provided.
for the second, I would not consider her question from a layperson wanting the standard layperson response. I guided her to more suitable books that would provide more technical answers should she want to research, as I see it she asked a scientific question. Years ago this industry had all sorts of 'laypersons' as the only ones even trying to provide information and there is much wrong information in them, so what was done or said years ago by what ever 'experts' at the time doesn't usually apply here. If a person wants to interchange poisonous and venomous it won't bother me, you had already told her of the other thread so I didn't need to repeat that. Provide whatever level of response you wish to a question Joe, but don't criticize mine.
