>>14201290#2 is an exaggerated strawman that was popularized by (((Noel Ignatiev))), who was a biased anti-white ideologue (like most Jews). Irish, Polish, Spanish, etc., were all considered white or else they literally would not have been allowed to become citizens under the 1790 and 1920 immigration acts.
A problem with NPCs and leftists is they just accept establishment takes on all issues, without realizing that most modern media and social science is just Jews circeljerking each-other.
