I don't really see it as a justification of mass migration, but I do see it as an argument for treating migrants as human beings not cattle(or worse). There are enough politicians and people in general who think that the boats and people at the borders should be just shot at, that will stop them from coming surely /s. You see this sentiment everywhere, and the "Remember that these are people just like you and I" thought process is missing.
To throw more fuel to the flamewar, just look at the Israeli treatment of Gazans...
For a longer essay of the idea of "refugees welcome", from an Iranian refugee who with her parents got asylum in the US after asking many embassies: https://www.theguardian.com/world/2017/apr/04/dina-nayeri-un...
> But what America did was a basic human obligation. It is the obligation of every person born in a safer room to open the door when someone in danger knocks. It is your duty to answer us, even if we don’t give you sugary success stories. Even if we remain a bunch of ordinary Iranians, sometimes bitter or confused. Even if the country gets overcrowded and you have to give up your luxuries, and we set up ugly little lives around the corner, marring your view. If we need a lot of help and local services, if your taxes rise and your street begins to look and feel strange and everything smells like turmeric and tamarind paste, and your favourite shop is replaced by a halal butcher, your schoolyard chatter becoming ching-chongese and phlegmy “kh”s and “gh”s, and even if, after all that, we don’t spend the rest of our days in grateful ecstasy, atoning for our need.
They are people, without technicalities. And we have a lot in common. There are a lot of differences inside a country too. In my country far-right doesn't value women right, personal freedom and non-violence while most migrants I've met do.
Also the very definition of "valuing freedom" can be debated with widely different answers depending on the country or the political group.
I am not sure if there are any confirming studies but dehumanisation [0] seems characteristically enhanced in people whose focus is primarily on technology - on things rather than people. Moral disengagement [1] also seems to be a prevalent reaction to existential threat, which I think we all feel to some degree.

I hope the irony is not lost on you that dehumanisation correlates very strongly with a propensity to violence.
I read/hear this argument a lot in Europe to justify mass immigration, and it's very tiring. Yes, technically they are people, from the same species. Then about anything else is different.
One might say that difference in culture isn't that big deal. Except culture governs basically every social interactions. If your culture values women rights, personal freedom, non-violence, a different culture necessarily means differences one some or all of those points. So yes, other people are humans too, but do you really want to live with people that think women should have no rights, for which violence is normal behavior, which think personal freedom is nothing in comparison to their ideology or religion ? I personally don't and I would rather live with like-minded individuals.
