The new angle is anyone not wearing a safety pin is a bigot, racist etc. I have already seen teachers wearing the safety pin. With this definition, half the country falls in this category. It keeps the low info voter involved in going against Trump in big numbers.
Here's my idea of a symbolic safety pin. Freeper 3D-Joy used to make these for the DCChapter members who freeped Walter Reed for seven years, countering the leftie anti-war loons.
