[EDIT: It appears that thre3e created several accounts to promote eir own post. I'm leaving this here, but I won't be engaging further since it doesn't appear Tamara is a unique user.]
Fair enough. Perhaps a better summary of thre3e's sentence would be:
I feel that some people depend on religious laws and expectations for behavior, and some people feel compelled to spread religious memes (either to bolster their own authority or that of a higher power).
(I would later develop the specific examples of "sex-related, murder-related, and god-worship related behaviors.)
You're probably right that thre3e's declaration of "certainty" was intended to signal the basis for eir assertions, but declarations of "certainty" set off alarm bells in my head, especially when they are presented without evidence.
But my intent isn't to put words into thre3e's mouth; if I'm not expressing eir ideas properly, I hope ey will correct me. I'm just trying to express what stylistic issues with the original may have detracted from clarity.
