Your bias is talking here.
"They didn't show up = they don't care" is a pretty huge leap to make, and doesn't prove anything per se.
The only reason you didn't see the rest of the Marvel Universe - Avengers included - react to the X-Men disappearing or do something about the X-Men disappearing is because the X-writers didn't include them in the story, the same way you don't see the X-Men show up in the recent crisis the Avengers had, or the ones faced by whatever other Marvel heroes are facing at the moment.
Marvel is a shared universe with multiple IPs, you can't expect it to revolve around the X-Men, it's that simple.
I stand corrected, you were right: icefanatic did factually say Krakoa was wrong.
My understanding at the time of that post was that Krakoa was wrong for the X-Men though - to either be part of it or to support it instead of fighting it since, as a concept of a mutant-only country, it goes against what the X-Men used to believe in and fight for: coexistence, id est a society where mutants and sapiens would be equals.
Hence the answer I made to you when you reacted to it.
And I'm not icefanatic so I can only infer so much from his position but that's still about the X-Men's involvement with Krakoa and the general direction it's taking, much like what are questionning other posters in this thread.
