If I let someone borrow my truck (which I do, mostly through family and church) and they did this to my Scott Walker sticker, permission to borrow my truck would be revoked.

It’s an insult to borrow someone’s property, and then use that property to advocate the property owner, who graciously let you use the property, be subjected to the slavery of Democrat tax and spend policies.

It’s the moral equivalent of returning the borrowed property with damage and then not making good on it.
