Yes many incels use that word, but it doesn’t mean the word itself is bad. “Males” and “Females” are words we’ve been using for men and women for generations, but now that a few jerks online used “females” it’s now considered some “bad” word. Take this post for example. It’s a WOMAN referring to HERSELF as a “female” (which is totally normal), and you’re still in the comments saying “only incels say female”. Ridiculous.
if we wanna get technical, it’s also poor grammar to refer to someone as a male or female. “Male” and “female” are adjectives and not nouns. So she could say “any other female people interested,” which is technically correct but sounds really weird, which is why we have the term “women”.
