It was about those who refuse to assimilate
For Endecja , it wasn`t enough when Jews assimilated - they were still treated as Jews, not Poles. They also had to adopt the nationalist antisemitic policy of Endecja which only acknowledged Jews who ""identify themselves completely with the national aspirations of our people and share them even if this calls for a limitation of the social status of the Jewish element among us".
Such a prerequiste of Endecja didn`t only concern Jews - also Polish political rivals who disagreed with Endecja nationalist opinions, were not good Poles. The only good Poles were those who identified themselves completely with its nationalist views.
as if that was a main issue
If you try to say it wasn`t, you are lying. Because it was. Dmowski was the main ideologist of Polish antisemitism.

he was, above all, a political writer. Sometimes he even wrote several texts a day. Antisemitism was fundamentally present in them and significant, from the 1890s, that is, from the moment when modern Polish nationalism was born. Anti-Semitism in Dmowski's writings grew more and more important with each passing year. It can even be checked statistically.By the way anti-semitism was a norm everywhere at the time
Yes, true. But this is a polish forum and we are talking about Poles and Polish Jews. Ha!
