I don't see how this is a counterpoint to my opinion. You can cultivate the generosity of natives to be open to immigration to whatever degree you think is just (e.g. by declining to use mockery/hate as your default position toward anybody who thinks there is any problem with the state of immigration), and you can do that regardless of your generosity level toward a political party that on average is more conservative or more hateful on immigration than the other. But that seems obvious, so I'm not sure what you're saying.
