I'm less certain about the hospital incident and overall left-vs-right bias, but I can tell you: Wow, Labour is really, really good about sounding the chorus "we're being unfairly targeted! smears!" whenever there's a new story that another MP has resigned over the party's systematic antisemitism (or that someone who was fired, ostensibly to actually deal with anti-semitism, has been mysteriously re-hired).
(Our local "anti-Zionist" friends in Labour will mod me down for this, I know.)
The current Conservative leader has called Muslim women "letterboxes" and black children "piccaninnies" [1] with "watermelon smiles".
Maybe someone has made a systematic review of the reporting of Conservative and Labour racism, and the reporting of it, but just throwing up a statement like yours, without also including the racism of Conservative party members/leaders, is just fuelling the fire of hostile debate.
There will be racist people in both parties. Step back, and compare the depth of the racism and the number and influence of the people involved.
Trust me, I am always glad to say that the island's politics are a poorly contained dumpster fire, and point out the big stuff, like the Windrush scandal, or the English-proficiency-test scandal (not the original cheating, the Home Office response where they told thousands of international students their tests were invalid and they were subject to removal).
But if we're playing the "which one is really worse?" game, instead of striving to better either, we've lost.
