That's not the whole story. This user said they hated white people and that they deserved the worst, except the comrades (the good ones... ugh) in reaction to a Reddit post about the recent migrant wave in Italy (the things said in the aforementioned post were indeed vile). It got reported, and a mod made a post to make fun of the report, stating that you can't be racist against whites. Some 6chan users justifiably didn't appreciate to see one of theirs perpetuating the same prejudice-infused language used by racists, and where labelled "libs" as a result.
That's what Othello is crying about here: not being able to handle being called out on their prejudice. A real shitshow.
Typical ML. If there's something they like more than a good purge, it must be to justify it.
