No, this was the right comment to respond to - your comment lacked empathy to why people might become migrants and reminded me a lot of Ebenezer Scrooge commenting on the poor without empathy to the fact that he was contributing to their poverty.
Us first-world nations play a large role in the global warming that drives climate refugees… I think it’s extremely immoral to just put up a big wall and tell people fleeing desertification to go somewhere else after making their home uninhabitable.
