It's called a balance of consideration argument, sometimes also "conductive argument".
Obviously, the legal question is different from this, IANAL and I don't even know if lawyers use conductive arguments in this way. The judge in this extradition case certainly didn't, but that's not surprising since her job wasn't to judge Assange's actions.
Let's not even get into his work laundering Russian hacked docs to damage the US, and then repeatedly lying about it.
He also is credibly accused of being a rapist.
The US has done some bad shit, no doubt, but that doesn't make Assange some saint. He's a bad dude.
While the rape accusation was retracted.
There's no equivalence of a proven fact vs accusation. Assange is unquestionably on a moral high ground here.
and Not even going to respond to your whataboutism here, just lazy argumentation.
In this case, the UK should not only consider the extradition request itself, but how they stand with regards to the US and their war crimes. And when it comes to war crimes, for the UK to be silent is to be complicit.

It comes from not understanding the difference between logical entailment and logical equivalence when given a set of premises and a conclusion. I'd've hoped programmers would have taken enough discrete maths to know this.
It’s not that I haven’t - but I’m 8 years out of uni and have completely forgotten how to apply Modus tollens and I suspect I’m not alone.
