Actual libertarians support people like Bernie Sanders. (Yeah, he's big on social programs, but he's also bigger on civil liberties than most Democrats, let alone Republicans.)

Politics are more tribal than ideological. Most people just repeat the slogans of their political tribe without putting too much thought into it. So calling out hypocrisy does nothing, most of politics isn't really about having a consistent ideology.

RNIB Scotland Director, James Adams, said: “Traditional black and white pedestrian crossings offer high contrast, which is essential for people with low vision to detect and cross roads safely. Designs and colours which are not consistent with traditional designs could cause confusion to people with sight loss, and to guide dogs which are trained to stop at crossings.

You'll also have to train dogs to recognize both approaches because the starting color will be different.

They technically are unsafe. They screw with Seeing Eye Dogs.

I think this might be true. Do you know of any published studies on this?

Oh the colorblind seeing eye dogs? 🤔
