Being on Mastodon means I can be the first person to use hashtags like #TheXMen

Since signing up for #MarvelUnlimited I've been catching up on #TheXMen. I've read X-Men off and on since 1982 and I barely grasp the continuity. I presume new readers check in on the Marvel Wiki 3-4 times per issue.
Also, Marvel has no idea what 'mutant' means.
