I love and hate the evolution of the use of the word 'bigot'.
Such folks engaged in purity policing throw it around like it's just another word for 'bad person', but almost every use of it I see is highly ironic.
The dictionary definition is 'a person who is intolerant towards those holding different opinions.' Almost everyone I've ever seen calling someone else a bigot online was using it to shame or beat down those who are not displaying bigotry, but merely different opinions.
They may have been objectionable opinions. They may even have been racist or sexist opinions. But never have I seen 'bigotry' applied correctly, and usually it seems to be applied by people unaware that they are the bigot in the situation.
I suppose in time the original meaning is lost, and we are left with just another insult. Which is a shame. But in the mean time I get to enjoy the irony.
