A person who criticizes or reduces the reputation of someone or something; someone who makes negative comments about others.
From detract + -er (agent noun suffix). The -er ending identifies someone who performs the action of detracting.
A detracter is basically a hater with a fancier vocabulary—the word is useful in formal writing because it's more specific than 'critic' (critics analyze, detracters just tear you down) and more dignified than 'hater.'
The suffix '-er' conventionally marks agents; '-ress' marks female agents (detractress). This gendered agent nominalization reflects historical erasure of women's active roles as critics and opponents.
Use 'detracter' for all genders. The '-er' form is now standard and gender-neutral.
["critic (more precise)","opponent (more neutral)"]
Women have long served as critical voices and intellectual opponents; the '-ress' suffix unnecessarily marked them as exceptional rather than normal.
