Nullius, is creating his own straw man, but does not realise it. Suggesting that plagiarists face a ban, (the most serious possible punishment) is not defending them. Or excusing them from punishment!
Empathy alone, is not something that should ever be punished.

It is entirely inline with my own views: that a starving man thieving a bun for his family to survive, should face the same punishment as the wealthy man, for committing the same crime. However, posting pics of his starving family and making fun out of his reasons, or excuses, for doing so, is not something I would engage with. I would perhaps  speak out against this. It portrays a negative and nasty mob.  

Writing skills? The original nullius (from reading his post history) is very unlikely to have stooped to such a retort. The OP is not error free to my own eyes.
Saying he believes ridiculing their excuses is in poor taste, is not as nullius claims and attempt to justify and excuse. The suggestion of a ban clearly demonstrates he believes there is no rational or excuse that should prevent the correct punishment. Would nullius return simply launch into a silly and petty attack like this.
If this is nullius, then apologies for suspecting otherwise.
