Honestly the sheer whiplash of going "caring about Palestine is virtue signaling only" and litterally in the same sentence going "Ukraine more important" is just perfect
To be fair (and balanced), for casualties as a whole, 10x is an accurate figure if you take western news sources at face value.
In the Russo-Ukrainian war, the amount of disinformation makes this staggeringly hard to know; Adding up the estimates gives ranges somewhere between 150,000 and 1,000,000 deaths. It's important context to note, though, that these deaths are overwhelmingly military.
In terms of just civilian casualties, Palestinian casualties are 2-3x higher, in less than a quarter of the time, with less then a tenth the population.
Civilian casualties in the Russo-Ukrainian war are very roughly estimated at 30k-50k, out of 37m over two years. Civilian casualties in Palestine are at a minimum of 110k out of 2,300k in 5 months. Even if the IDF's own numbers are to be believed, that means >90% of casualties are non-militant civilians.
If you believe western news sources, Ukraine does have about ten times the casualties. So in fairness I don't think it's a bald-faced lie by this guy in particular, more just western governments.
