It may seem that this is relative (and from a humanitarian perspective, it may very well be), but from a marxist perspective this is not a relative issue. While the owning class can have free flow of capital, any restriction on the freedom of movement is bad, as it creates low-cost-labor zones which the workers are unable to migrate from and can be exploited by capitalist enterprises. Advocating for free-movement of people is pro-immigration, advocating against it is anti-immigration. And advocating for forced removal of people (i.e. deportation) is both anti-immigration and anti-human-rights.
