as annoying as it is, you need to create your new account, then migrate the old into the new
You should keep followers and following
Everything else is lost in the process (you can export your archive in your settings to save that data first)
How to migrate

What matters is not whether or not mastodon takes off. What matters is whether or not Fediverse takes off
Now as far as your political experience, I can say my last two instances have had very little to no political content. My current instance is my own, and we outright do not allow political shit lol
But even when I was on mastodon.social, I did not have lots of political content, I wonder who you followed or what hashtags you followed that were politically influenced?
Are there political servers? YES! Just as much as theres servers about cats, coffee, reading, art… There’s servers for anything, this is WHY you pick a server, you have the freedom to be part of a community of your choice and filter out junk you dont care about!
I promise you politics exist on every single social network.
Mastodon’s home feed does not show you something you did not follow (unless someone you follow boosts it)
And even then, the filters feature is dope AF, I have a filter for common political terms, and youtube/twitch links cause I dont really care for peoples live notifications
My experience is very curated, and very in line with what I want to see 👍
