It has to be asked, are students from Ireland, UK, Germany, Norway getting the same email ?

For some reason I really doubt it.

Not really in favor of deporting them (except maybe a few that did cross the line), but it always seems incredibly hypocritical to me that these people actively choose to immigrate to the US (a colony that wiped out the local population) and yet claim that israel has no right to exist because it's an "evil colonial project" (despite jews being native to the land).

Not only Jews are native to the land.
