From Webster dictionary. Respecting: about or relating to (something).

"Congress shall make no law respecting an establishment of religion..." Just like I don't want Islamic based laws, some people don't want christian based laws. I don't support gays, never have. But I see what the road could lead to 100-200 years from now if we let religion-based laws govern the free nation. Seeing how ISIS uses religious beliefs has helped me come to this stance.
