I am a bit surprised that this has to be elaborated here (as stories like the following are posted here fairly often), but here you go:
- musk openly sharing a German nazi party stance and equating migration with “invasion” [1]
- he allows hate speech to proliferate on twitter [2]
- he regularly shares conspiracy theories that are common in right wing circles, eg. casted doubt on the fact that the shooter of Allen, Texas was a white nationalist (even though he literally had swastikas tattooed) [3]
