In my experience it was x-fans who weren't jerks to Runaways fans that's been a minority, not other way around.
And maybe some questions don't need to be answered? Why X-Men won't show up in Runaways? Because X-Men story sucks. This is like stopping a book I actually want to read and have to listen to Jehova Witnessess sales pitch without being able to talk back.
I keep away from all x-books. I'm not reading nor supporting them. And this is a second time, after Gwenpool, these fake minorities force their crap down my throat.
