yep, agree, a business or person's ethical standing is very important when looking at a business or person's credibility, as is their history.
This is why it is important to look at posting history on CZ and other forum sites. I don't tend to give much credibility to people whose posts consist of constant personal attacks on others, and little other information.
As it says on the top of the Debate Forums , attack the message, not the messenger. This seems to be ignored much of the time, as is the admonition that the first to start name calling loses the debate. Its sad to see so many adults having to be reminded of this.
