I think the first one's good to have: it's positive, and gets people somewhat acclimated to the whole karma thing. I really don't know what to say about the 2nd; if there were a perfect boilerplate response to religious criticism of rationalism, I suppose this forum probably wouldn't exist. Yours is still as good an effort as any, though could we possibly take debating evolution completely off the table? That and calling any scientific theory "just a theory"?
