GP is a man of strong opinions. He's not advocating violence against anyone for their choices, just stating his thoughts. No one else has to support nor agree with GP's thoughts if they think differently.
I'm beginning to think e-bikes were invented to give cyclists something to argue about :-) I own an e-bike but don't ride it much and it's just an expensive toy that I don't ride because it makes me lazy. However, if e-bikes allow less-able people to get out on bikes and, as long as they actually have to pedal to make them go, then they aren't completely evil.
