Surely there's room for people to vehemently disagree without being called fragile and "unable to take it".
I think life extension is great, but I think leaving because people disagree with that is close to the definition of "unable to take it".
I'd assert the latter...
If someone is unable to find people who agree that helping people live longer then perhaps there is something else going on, because that doesn’t seem a hard argument to make.
OTOH, if they are making the argument that Hitler was correct, then yes I would unashamedly hope there are social consequences.
