I am,— Ilhan Omar (@IlhanMN) February 24, 2020
Easily triggering conservatives, Right wing bloggers, anti Muslim bigots, tinfoil conspiracy theorists, birthers, pay me a 💵 to bash Muslims fraudsters, pro-occupation groups and every single xenophobe since 2016 😆 pic.twitter.com/SffIqUT32I
She is saying that critics are bigots against Muslims or black people or immigrants.
This is essentially her inoculation against criticism. It isn't about her words or ideology or her own bigotry - she is immune from attack because she can play the racism card.
So Omar, and the people in her circles which increasingly resembles the entire American Left, refuse to engage on the issues - her antisemitic statements, her offensive positions, her links to pro-terror organizations, her pretense of being feminist while refusing to admit misogyny in Islam, her paying a large salary to her lover and other corruption that is being revealed - and instead deflect criticism by labeling her opponents racist.
It is probable that this tweet was meant to be a response to the release this week of a book by Benjamin Weingarten about Omar and the threat that she represents.
The last thing she wants is for people to read it. For Omar, it is much better to imply that anyone who reads the book is vile.
