Israel was created by ethnically cleansing Palestinians during the Nakba. That's not a democracy, ethnically cleansed Palestinians aren't even allowed to live on their land, let alone vote. That's not including all of the Palestinians that have been straight up murdered.
In addition Israel is an apartheid state with many undemocratic features:

America was a democracy while we were exterminating our native population. Democracy is a system of government. Voters can democratically vote for terrible things.
Israeli Arabs are allowed to vote.
> Israel is an apartheid state
This is a valid argument, though still stretched–America didn't cease to be a democracy while we occupied Germany and Japan.
