Easy phrase for rude folks to trot out when someone raises ethical/moral/legal concerns. Quick little rationalization:

_other person says they care about thing I don't that admittedly does sound good, so it has to be wrong to have mentioned it - I can't just say I don't care about the good-sounding thing_

(Of course, on the internet, people will end up playing make believe with their values, but it shouldn't be the first assumption. Or maybe it should, but with a hard second look.)
