Challenge the morality of a politician's stance on a given issue and criticize current American politics as normalizing discriminatory behavior.
The Republican women senators you mention stood up because their constituents raised holy hell. I saw Susan Collins defense of Jeff Sessions for the position of Attorney General--the man who is the chief architect and executor of Trump's virulently racist immigration policy. Her defense of Sessions made it impossible for me to have anything but simple human respect for her. She's not "honorable" because defense of racists is not honorable but unseemly, undemocratic and grotesque. I'd be interested to know what part of Trumpian policy you agree with. I'm sure the Republican agenda, which is primarily racist, will make great headway in 3 years. Trump has already normalized racism in front of thousands of boy scouts. All the world is observing Americans and how they are normalizing racism, violent sexism and homophobia. When they think of Americans they now think of Donald Trump--a liar, sex abuser, cheat, and a disgusting lout. Donald Trump, king of the Americans.
