Well....no. But thanks for being generous. There are intersubjective things--like words--but that's not what I meant.

I was not suggesting that morality depends upon it being sufficiently popular. It is objectively wrong to kill someone because and only because they are left handed.

I do not care if every single person on the planet holds the opposite view, they are all wrong. No amount of personal, subjective views on it can alter the objective nature of it--being left handed isn't morally relevant and to kill someone for a morally irrelevant reason is immoral.
