Christians and religious people in general make up a substantial portion of charitable work around the work. So I think that easily disproves your claim that they cause nothing but pain.
Really your statement just comes across as childish and uninformed probably because of the large amount of propaganda you consume from places like this.
Why shouldn't you hate 55%+ of the world? Do you really believe more than half the people in the world contribute nothing but pain?
Also why didn't you include Jews? They're the root of Abrahamic religion and currently the "Jewish homeland" is engaging in genocide.
It's just silly but also worrying that you could have such a skewed view of reality.
The people "ranting about cancel culture" are not the generalized group "Christians." What can you do though? Lemmy fully embraces hate against Christians.
