On the other hand more news like this might get people away from far right.
Xenophobic arguments are not "about the numbers" or rationality. They are about fear. You can deport as many people as you want, the argument will not go away, as long as there's a single migrant anywhere (and possibly beyond). Also, voters tend to be more right-wing if they don't know any migrants themselves because either there are few/no migrants where they live or they're segregated from them.
Also look at Biden or Obama — they had more people deported than any US president who came before them. Biden even instituted an "upper limit" on migration recently. Yet, they will still be attacked as "weak on migration".
The only way to win (as a society) is to integrate migrants well. And to make sure people don't need to flee their home countries.
