Why don't global warming deniers understand that greenhouse gases are dangerous?

dangerous to whom, and SUV's contribute to pollution but a chevy impala doesn't, what in the world are you talking about. if you don't like SUV's then don't buy one, but who are you to tell me not to buy one. and I do deny global whatever the new buzzword is today. my suggestion to you is stop breathing as you are exhaling that terrible pollution co2 at around 40,000ppm with every breath
