clobber text
n.— «Reading over recent postings on homosexuality, it has become apparent that some posters have a little resource of 6 to 8 Biblical texts which they use to “clobber” pro-gay posters. The Levitiucs texts and Romans 1 are most prominent, but some posters cannot let go of Genesis 19 [the Sodom story] either.» —“The Bible is Not a Collection of Clobber Texts” by Paul B.
