Respectfully, this is bullshit.
O'Brien growing a spine would have involved calling out Republicans and their policies at the RNC.
The Republican Party, as it exists under the leadership of Donald J. Trump, is a party of and based around an ideology of bigotry, marginalization, oppression, and hatred.
O'Brien's speech and this announcement serve as a tacit endorsement of that ideology. The leadership or the International Brotherhood of Teamsters is telling the world and the rank-and-file that the repressive, Neo-fascist ideology of Trumpism is at the very least acceptable to them.
There is zero chance that the right to organize survives a second Trump administration.
All O'Brien did here was throwing out female, PoC, immigrant, refugee, migrant, and LGBTQ+ brothers, sisters, and family under the bus.
It was the opposite of Solidarity.
