Part of the issue is the label genocide is applied so liberally as to lose meaning. We're seeing similar devaluation of previously potent labels like "fashist"

It then becomes easy to say "I don't engage with fashists / genocide supporters / whatever" as an obvious justification for staying in ones bubble when in reality that label is so overused for people/events that say 10 years ago would have obviously not been labeled this way.

That is to say: when everyone is fascist/ genocider you have an excuse to not debate with anyone but that's not good for you.
