What evidence do we have that Hamas raped or used sexual violence and why didnt they do that to the hostages while they were in captivity ?
You indirectly answered the first question you asked, with the second question you posed. That is called inductive logical reasoning. They simply didn’t.
No Israeli women were raped by Hamas.
No Israeli babies were beheaded by Hamas.
No Israeli babies were baked in ovens by Hamas.
In contrast:
Palestinian babies were beheaded by Israeli missiles.
Palestinian babies were burned alive by Israeli missiles.
Palestinian babies were starved to death by Israel’s siege and imposed famine on Gaza.
Both Palestinian women and men were sexually abused and raped by the Israeli occupying forces.
In conclusion: EVERY ZIONIST ACCUSATION IS A CONFESSION.
