Do you have a definition of fascist you approve of, or would argue for? It’s absolutely true that some people throw around words as dismissal but that doesn’t mean we just all throw up our hands and say all words are meaningless.
Ultimately, the fight over ‘fascism’ is a fight to define ‘fascism.’ Having no definition is not a position to argue from. It’s ignorance. Arguing on behalf of ignorance is just noise. Even if no one else shares your definition, decide what it is, then argue for that.
Absolutely. I was an absolute loner for the better part of a decade. Then my depression just disappeared. I joined a community around a streamer and had loads of fun. Just find the intersection between your preferred subject (literary analysis, anime tiddies, etc.) and your preferred communication method. (Text forum, voice chat, real life meetings, etc.) You’ll find at least someone you can hang with, maybe more. Just go at it with openness and joy.
