I've read some third-party reports. The stare-down thing was not covered in what I read. The part about her getting wet was mentioned as "crass." I've experienced this phenomenon myself, so I can say that its a credible claim, especially if the confrontation occurs in public. Olivia Rodrigo is target one (due to admitted plagiarism of Swift's music) and it contains a very violent intention on Swift's part. The second one is supposedly a diss of Charlie XCX (a response to a diss track toward Swift called "Sympathy is a Knife"). Again, this is from third-party entertainment industry reporters, so I have no idea as to the actual truth of these allegations or speculations.
Swift is absolutely a passive aggressive personality who is mighty mouse in her head, and a punching bag in reality. For sure, Charlie XCX would destroy her in an IRL physical confrontation. Olivia Rodrigo might be able to overtake Swift, but it would be a tall order (pun intended). Olivia is pretty slight and only 5'5 to Swift's 5'10.
I would think it would be good for us fighters (in terms of general acceptance) to have some superstars going at it in the public sphere.
