Woodie, as I stated on the discussion board, the word cactuses, as a plural for cactus, is quite acceptable according to the dictionary.
Also, 'these low-lives' is correct in this context. However, 'this low-life' could also be used in the plural, or to relate to a collective.
If you are going to chastise anyone, I suggest you check your facts first. Just saying......
