Because it does matter, motherfucker has millions of people listening to him and a worldwide social media that he controls. Even if his opinions are trash, he amplifies and spreads this garbage, and gives a platform for the scum of the earth who wouldn't have it otherwise.

Fucking Henry Ford of our age.

This isn't Tom the small business accountant from rural Ohio commenting on Germany's immigration policy on a facebook post. It's someone who controls more money than the GDP of multiple entire countries, and who has already shown an interest in using his companies to influence geo-politics based on his opinions in the moment.

If anything, you should be concerned that a single individual can make choices about global politics without discussion or legal safety guards - which has historically caused some issues in the place that the AfD comes from.

To be fair, this is a private American citizen with close enough ties to far right politicians he hosted the campaign launch of one, who’s whim personally controls a major space launch provider and a site that sets the terms of public conversation and normality for a terrifying large number of people, and ohh ya, in an economic system based around the idea that the person with the most capital gets to decide what to do , well he has the most capital.

Will there be media coverage of my posts on the topic

If you're an influential billionaire then yes, there will be.
