In case it wasn't already obvious why Farage and his party are spreading misinformation about the climate crisis and trying to blame the most vulnerable for the problems caused by inequality - they've just received a record donation from a jet fuel multimillionaire!

An Oregon pilot program giving cash to homeless youths sees a staggering reduction in homelessness. The program gave participants $1,000 cash payments each month for two years, and at the end of the project's first phase, 91% of participants reported being in stable housing.

It also found only 7 of more than 400 stopped taking HRT... and of those that did, 4 still identified as gender-diverse.

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area.

There is no possible justification for limiting e-bikes to 15mph but not cars.

There are many real inequities that keep kids, especially girls, out of sports, and yet strangely we never hear the Save Women's Sports crowd talking about those. They're not running youth clinics, or gathering equipment donations, or doing anything to address really obvious barriers. Weird, huh?
If fairness in sports is something we cared about, then all private coaching, camps and all the other ways parents money give some kids an unfair advantage should be outlawed. But fairness has nothing to do with this because no advantage has been proven in trans kids.
