More people need to leave the culture of consumerism behind in order for any meaningful change to happen.

Probably true. I'm not going to argue; I also feel that consumerism is generally harmful to society.

Cyclists are putting themselves and everyone else at a greater risk when they decide to try and share the road with motor vehicles. [citation needed]

I, too, once thought being forced to slow down and pay attention to my surroundings would put people in danger, but I have since grown into an adult with children and neighbors I care about. Why do you think roundabouts are safer and less congested than traffic signals? I'd be extremely unsurprised if road sharing actually made them safer overall.
