The line from the passage that serves as an example of antithesis is:
(2) "When we are erased from our history books, we are made invisible to our own society, and the result is, as Congresswoman Meng so eloquently put it, 'we are perpetually made to feel like foreigners in our own country.'"
This line presents contrasting ideas of being "erased from our history books" versus feeling "like foreigners in our own country," highlighting the juxtaposition between being part of the nation and being perceived as outsiders.
