Ovens What's the difference between a pizza and a Jew?. Pizzas don't scream when you put them in the oven!
Are you referring to what happened during the holocaust?
Yes! I hate jews, they are just lesser people.
The holocaust was a traumatizing event for many people and it can be hurtful to be reminded of it even by mentioning parts of it like the ovens. You should go to a holocaust museum to understand what happened there and why it can be hurtful.
