I'm fine with someone claiming to be Trump or Putin or Starmer or even this guy needing to prove that they are who they say they are. In fact, I'm good with that.
But anonymous stuff online? A lot of us aren't on Facebook/Twitter because we don't want to speak as ourselves, we want to speak freely anonymously. And like they say, a claim presented without evidence can be summarily dismissed without evidence, a statement made by an anonymous person does not have the same weight as someone who is tying their statement, and in fact their history of statements, to their true identity. And maybe we don't want or need it to.
