If Hamas does exist, does it reduce the number of atrocities against civilian Palestinians?

No?

Then why are you unable to condemn their especially brutal and egregious atrocities against civilians, especially when that is the topic?

It's really really easy if you actually care about civilians.

I can condemn Israel's atrocities against Palestinians easily, look: I condemn Israel's atrocities against Palestinian civilians.

For example, I condemn Israel for launching highly destructive weapons against targets in civilian areas, where civilian casualties are unavoidable and the target is not of critical military value.

Can you condemn anything Hamas has done to the population it has political authority over, or to Israeli citizens?
