Yes, these people have influence to the extent that everyone else accepts it. But they don't shape anything.
The cow fart nonsense is just talk. It might even become law. I think in Denmark, if I'm not mistaken. Shortly after that it will be just a short funny anecdote of the socialists failing again to centrally control complex systems.
Don't get me wrong. These people cause damage, but I reject the assumption that they shape anything. They're just riding the wave and making a mess, but they have far less power than they'd like you to think.
