You may not worry about those things, but a female voter sees these things and think "Why would I vote for someone (Starmer) who doesn't even know what a woman is?" Other people, male and female will think "how can they run a country when they cannot even dress themselves coherently?". It symbolizes their ineptitude. Hence they keep losing general elections.
Why on earth would the Tories call an election? They have a massive majority until 2025. You can't keep re-running votes just because you lost, I'd thought you Remainers may have learnt that by now...
Why do I mention Brexit? Because Truss showed her competence in securing many trade deals, quickly. I don't need you to mention it, I can do it all by myself since it is relevant to the topic on hand as we are discussing her credibility for leadership and her role in securing the trade deals demonstrates it.
It doesn't matter how bad Truss is perceived to be by the far left. Until Labour ditch the likes of Starmer, Rayner, Abbott, Lammy, Nandy, Thornberry etc. they are pretty much unelectable, so make yourself comfy and strap yourself in for the ride.
