I don't think OP has lost any credibility, she's spoken clearly and has good arguments that resonate if one is a feminist and left-leaning.
But, is this the American Revolution 2.0 where we fight off the British oppression led by KJK? No, I don't think she has an army that large.
As an American who can and will vote Harris in large part because I'm a feminist who cares not just about abortion rights but health care (we don't have the NHS) and climate and gun control - all which negatively impact women, it's rather amusing to think KJK thinks she can influence US voters.
While there's a subset of non-US KJK supporters who are clearly her flying monkeys on every thread about her, I'm pretty sure most of her ardent supporters can't vote for Trump if they wanted to.
Frankly, you have more to worry about KJK in the UK as that is where she hurts the GC branch of the feminist movement most. Most people in the U.S. know who Riley Gaines is but have no clue about KJK. (And while Gaines and I disagree about Trump, I admire her professional behavior and strategic focus on getting men out of women's sports).
KJK tried to take on America, but like King George, it didn't happen. But we are open to another Beatles invasion
