Constantly? Well if you said often, probably. I constantly talk about politics. Get your facts straight mate.
Anyway. I am not going into a really long discusion. All I am going to say is, that everyone will become a climate "activist". Just give it a bit more time. When the effects really start to hit everyone. Because from now on? Things are going to get progressively worse. And then the crying will reach to the sky, why oh why is this happening! Why did no one do anything aginst it!
The thing is, you can call those "activists" hypocritical all you want. But, 1. It does not change what's actually happening, the collapse of the eco systems. And 2. If you think they are hypocrites for driving cars, then you simply haven't been paying attention and you should get your self acquainted with what they are actually protesting against. Crying about their hypocrisy is like standing in the middle of the courner and yelling, THEY TAKE OUR JOBS! It's silly populism.
It's not about the world ending. Fuck, if a meteor would hit this rock it would be quick. But this bullshit with the environment is like cancer. That's the problem. It doesn't just "kill" you. It kills you in a really misserable and fucked up way.
