It's kinda funny that earlier you were accusing me of gate-keeping when now, apparently, I've not been doxxed enough to render a valid opinion. Unfortunately though, I'm going to share it anyway.
Look, if it's not "fun", if you're not getting enjoyment out of it - if it's, in fact, a detriment to your well-being, stop. It's not an obligation, it's not essential, it's not your livelihood. It's a pastime. All of this, all of this, is superfluous. It's not brave to jeopardize yourself over a video game, an optional crusade that eats away at your welfare for the sake of sticking by a fictional character is not worth lauding. It's myopic. You want to be the bigger person by being stalwart in the face of haters, be the even bigger person and don't hinder your psyche over randoms on the internet.
All the Ridley, K. Rool and Banjo fans could've just dropped a vote for their character on the ballot and bounced completely, and they'd still have wound up in the same position. Sakurai already knows Geno is popular, sticking it out is great if you're enjoying yourself, but if you're not, it's foolhardy.
And I know there's a... unique perspective inside your thread, but there's a pretty different vantage from all the other angles. You know how when you're super close to something you can only see what's right in front of your face, but when you pull back a bit you can see the whole picture?
Ultimately, people do face needless jeering in the fanbase, sometimes a lot, but I'm not capable of expunging negativity off the internet en masse. None of us are. What we are capable of, however, is autonomy, and anyone can leave at any time for any reason. You don't have to deal with the fanbase; exposure is optional. And mental health is a better reason to leave than a character is to stay.
