I didn't know the imagine phrase means it's stupid. I thought it's just judgment (e. g. imagine killing people). And I didn't even say it very seriously. I already explained the reason. If you care to actually be fair, read that

In this case I understand why people would respond negatively but imo rudeness and general toxicity is not justified. These things are always bad. Well maybe except the cases when the other side acts the same way or is just evil and you use toxicity as a form of terminating the person's ability to hurt others. Though if what I said really was extremely rude, probably it's fair idk
