Spraying paint into the jet engine of a military aircraft is not "terrorism". It may be criminal, but it was not in any way a violent crime. Given that it disabled the aircraft, it counts as more than mere vandalism, but calling this an act of terror is outrageous.

The logic seems to be that Hamas has committed terrorist attacks against Israel, and is also the government of Palestine, so anyone fighting for the human rights of Palestinian people is actually materially supporting Hamas terrorism against Israelis. That does not really track if you know anything at all about what's going on in Palestine right now, or what people's actual criticisms of Israel are.
