I guess my feeling would be to stay quiet when people seem to be saying the right thing, but then hold them to it when they turn around and chicken out.
Because by doing the opposite, and holding them to all the past, chicken-out stuff when they are saying the right thing, then you may give the ammunition to say “even when I say the right thing, its never enough for some people”.
Just a thought really. Because I loathe OJ, and what he stands for, I am just trying to think of the most effective way to discredit. Sorry if I got the wrong end of the stick.
