The Precious Feet pin, one could argue, is not a political or religious statement of any kind, but rather a work of art unto itself. It’s an accurate reproduction of a pre-born baby’s feet at 10 weeks of age. When a person looks at those feet, it’s up to them how they interpret it and what it gets them thinking about. You are not making any statement other than to visually present a reality.
To the Left, the pin IS a religious & political statement. And it's a vile one to them. They recoil at the site of it! Like vampires to a cross! That's why the woman was booted out of the National Gallery of Art. A museum! - she got booted out of a museum for wearing a pin! Not a swastika, not a symbol of anything vile - but two tiny feet symbolizing Life. The horror!
