generically speaking yes i might encourage you to find a way to insult people without trivializing the experiences and loss of those suffering from the disease and their loved ones.
in the specific case where it is a descriptive metaphor and not an insult, e.g. “multiplies like cancer,” that’s probably fine. but if you’re using it as an insult, i for one will not come to your defense.
But I'm not sure how it trivializes it. Using it as an indicator of a bad thing is meant to indicate how much that thing sucks. You're calling things cancer because how much cancer sucks
Yeah honestly ml and world are probably about the same on the genocide denial front - they both have a handful of problematic users who are unfortunately very vocal - ml from the tankie angle, and world from the liberal angle
But I'd say the majority of users on both instances are alright, in my observation
