He's not arguing in good faith.
Here he's arguing that Hamas hasn't rejected anything, ie. they haven't rejected a deal.
Further down in the comments, he says that the Israeli deal is stupid, thereby admitting that there is an Israeli deal which Hamas is rejecting.
Check out his comment history.
The comment I replied to said:
30,000 people have died. 17 million people died in the holocaust. That is not on the same level and it is not on the same scale. 30,000 is a significantly smaller number than 17 million.
If you support the Palestinian cause, pretending otherwise is a home goal.
I get that it feels right, because people are understandably angry about all this, but it's not a winning argument. Quite the opposite. If you're provably exaggerating the scale of what's happening, it allows supporters of Israel's far right government to sow doubt and claim you might also be exaggerating about the very very real war crimes and ethnic cleansing they are engaged in.
