I really hope this isn’t the case here.
Wait. You really hope an entire collection of instances and, furthermore, the entire collection of communities within each instance, will have the same exact opinion, of -at the moment- being pro-Nintendo.
You really must be joking right?
There is absolutely 0 chance you will find one opinion spread among an entire community, let alone here in the Fediverse where it's multiple communities.
Each person has their own opinion and/or agenda and that's the best part. I really hope this side of the entire continues to not be able to be labeled a singular thing since that is immoral and outright incorrect, on all fronts.
So to answer your question: Who knows? To each(user) their own.
Every place is the wrong place to ask this question.
Putting a label or asking a community to reveal their manifesto is not a good look or how conversations should be started.
The correct thing to do is participate in communities you seem to like and if you find out that you don't agree with that community on one or more fronts, then by all means, please create a new instance and/or community on your own and run it according to your preferences. This is the intended purpose of the fediverse: If you don't like it, do it better by yourself.
I wish to hear all opinions in here by all kinds of people.
I wish to hear the worst and the best arguments on a topic.
Doing what you ask, as in join a pro-Nintendo community will 100% have a bad outcome since it will, by definition, be an echo chamber.
