As with most things it is a mixed bag. It has been both beneficial and detrimental to humanity. I am an atheist myself but I don't wear it on my sleeve. I don't define myself based on a lack of belief in leprechauns, so why would I for a lack of belief in a god?
I'm not sure. Doing Youtube has been really interesting because thousands of people have weighed in on their impressions of me. The vast majority has been positive though. So that's good.
