So: On behalf of myself, I'd like to welcome everyone on Mastodon, OSocial, and the Fediverse to your (newly realised|long accustomed) minority status.
Get used to it.
Get used to the fact that others are, perhaps, getting used to it. Some for the first time.
Some, with more than a little resignation, not.
But realise that, unless you want to want to use some very broad classifications, there are few actual /majorities/ on Mastodon.
If you're right-handed, dark-haired, probably.
