Calling for a ceasefire is basically pressuring Israel to 'turn the other cheek' and walk away.
This directly empowers Hamas.
You are telling them that murdering, raping, and brutalizing innocents has no consequences.
If you truly cared about Gaza, you would call on Hamas to turn themselves in and return the 239 hostages (who you constantly forget to mention).
This would not only end the war immediately, but it would also free Gaza from their Jihadist tyrants.
