I never argued that climate change isn't real or that nothing should be done about. My point was simply that when people behave in a hypocritical manner, they tend to lose all credibility even when they're right, and they hurt the credibility of those around them who are making the same argument. It's like an anti-halo effect. Every Hollywood actor demanding we take action on climate change while flying around in a private jet weakens the argument for real action on climate change. It makes the issue look like a vanity cause even though it's not. You see the same thing on taxes. You've got guys like Bernie Sanders out there demanding we all pay more taxes while he himself has a very low rate of charitable giving by most standards. He could also opt to voluntarily pay more taxes right now. Of course he doesn't, which again undercuts any broader point he may have. Human beings are hardwired to be turned off by hypocrisy.
