>"Property of [Biker's Name]." But sure, blue lives matter and all of that, right?

Tangentially related, US politics aren't actually divided into two neat sides. We say the American Left and the American Right, but there are a lot of differences of opinion within that.

Even within subdivisions it's split. The Christian Right makes up a portion of the American Right, but even within them they don't all agree. Some are staunchly against gay marriage, others allow them in their churches. Presbyterians and Catholics are often very different on their political and religious views, but they are both generally of the Christian Right.

Point is, not every person on the right believes "blue lives matter" because the American Right isn't just one opinion shared.
