It's not a term that needs replacing. Shorthand personality bins are not a void that needs to be filled. Classifying the speaker (whether with 'emo' or 'hipster' or 'feminazi' or 'homophobe' or 'fag' or 'geek' or 'jock' or ...) does nothing to elucidate the argument.
You do not need to classify the speaker. Your arguments are stronger if you do not classify the speaker. Classifying the speaker leads one to interpret an argument through one's preconception of that class of speaker, weakening one's listening and interpretation skills.
And, classifying a speaker aloud often leads your audience to classify you in an opposing class. Use "white knight" and many will classify you as a "bro". Use "homophobe" and get classified as gay or a militant feminist. Use "gay" and get classified as a homophobe. That leads to your audience interpreting your argument through their preconceptions of your classification.
In other words, classifying the speaker endangers your critical thinking, endangers your chances of being understood, and has no upsides.
