Compromising on legitimate issues to get a crumb of concession on other issues will only lead to sacrificing all your principles to meet fascism in the middle. Problem with leftist in Europe isn’t that they don’t compromise enough, problem is that they appear as single-minded by compromising too much and letting their detractors engage them on issues like Antisemitism and Trans rights. Meanwhile you can have literal Nazis in European right and its overseas supporters like court eunuch Elon cast a wide net and compromise on nothing manage to keep pushing the boundaries of acceptable and moderate fascism.
There is something very telling about Germany which patronizingly preaches about Western values and peace to Palestinians which get displaced and bombed regularly immediately have large portion of their country turn fascist as soon as there is smallest amount of societal disruption and violence, backing the party that supports the political ideology that caused said violence no less.
It also makes me respect those who suffer from some of the worst of humanity in cruelty and violence still embrace kindness and compassion first.
