Because supporting Palestine isn't hating Jews and posting people mugshot style on a website as anti-Semites because they support the Palestinian people right to have a nation and to return to the homes they were kicked out of is far-right. The same way wanting the Ukrainians to be able to go back to Crimea and other Russian-annexed lands is not hatred of Russians. And if a website posted mugshot style bios of Ukraine-supporters in such a way, we'd all know they are far right.
He didn't mention Hamas, or Jews. And what he said is not anything anti-Semitic either. It's also true. Under international law an invasion and occupation of one's land is a justified reason to launch an armed resistance. Like Ukraine did.
You may have wanted him to say, in that clip, "10/7 was justified" but he did not. He is simply saying that any type of amassing of arms will be seen by Israel as terrorism when they have a right to defend themselves. Do you think Palestine has no right to defend itself from Israel?
