It's not just drag queens who use the word Fish.
That's ok then. Lots of people reduce women to their 'smelly vagina' therefore that's ok.
You seem to like drag because everyone should be free to express themselves how they like, irrespective of the harm they do.
You earlier said Fish is just a word. Have you heard of hate crime? This is where you use 'words', bad words, against someone else. Standing up in court and saying 'they're just words' isn't a defence. You can get fired for using some words because they are considered hateful.
Referring to women as Fish, Cunt, Seafood Platter, Box and the plethora of derogatory, woman hating language, associated with Drag is disgusting and has real life consequences. They're not just words. People kill themselves because of words; it's called bullying.
The dehumanisation of women gets women killed and abused. It's a very real issue, not something to be dismissed as just 'word' or men being allowed to express themselves however they like. No one has the inalienable right to dehumanise others or to treat them with hate.
There are over 200 words in the English language that are derogatory towards women. How many can you name for men? Words matter. Fish is specifically associated with the Drag scene because it's a misogynist scene full of spiteful men who hate women.
