If your best friend was like this, would you let your children play at her house?

I have a best friend and neighbor her name is Eva. She likes Hitler but it's not her fault because her grandmother who raised her was a real Nazi back in the third reich and her grandfather was in the SS. My kids like to play with her kids but she always teaches them how Hitler was great and shows them photos of her grandmother and grandfather having dinner with Hitler, her grandfather getting an award from Hitler, etc. They play WWII battle games and they always play that the Axis is the good guys. And yesterday my kids came back from her house and they had little moustaches on sticks it was a craft project apparently.
