Biden thinks men can be women, so no he doesn't know. He's 80; I actually think he knows men can't be women but he's been told what to say on the matter. I bet he couldn't explain what LGBTQI+ stands for without a cue card.
Because they are both useless. One's mentally incompetent because of age, the other because he's not very bright.
They didn't do it with Obama. Even Trump can talk off the cuff on issues, even if he spouts nonsense on them. They seem scared to let Biden go off topic or talk spontaneously at all. He's the president of the United States and he can't be left alone with the press in case he goes rogue.....
Well, I disagree, but then I've made my position on trans rights fairly clear in the past. That's not what this thread is about, though I will say, again, that pretty sure he knows what a woman is, and what LGBTQI means.
Of course he's been told what to say on matters, because he's an actually intelligent person who comes prepared. Unlike Trump (or Johnson) who'd just make shite up and ramble on nonsensically. Biden has been in politics for decades, he knows exactly what he's doing and his team will know where his strengths and weaknesses lie. Plenty of presidents in the past have been similarly prepared, and if you think Obama wasn't then you're very much mistaken.
In any case, what does it matter? Why should he be giving out random press conferences left right and centre? Especially when the slightest mis-step will result in a trial by media, which achieves the square root of f*ck all.
As for his mental incompetence because he's 80, that's just ageism I'm afraid. My grandparents were well into their 80s before dementia sadly claimed their mental capacity, to use one example.
