Animal Wrongs Group: More than a few of the baseline-supremacist, deep green, or luddite ones, who support policies including exterminating all neogens, uplifts, and genemod animals as an affront to precious Nature.  For starters.

(There are perfectly respectable animal rights groups – say, the Galactic Friends of Life, who are willing to go to bat for habitat preservation, the avoidance of suffering, and the subsetted natural rights accorded to prosophont and merely sentient animal life according to its nature – and who have even dabbled with applying the same principles to wild a-life – but there’s also a lot of idiots out there who value the naturalistic fallacy a lot more than they do any actual animals.)
