Do you have a source for your claim that Uber is named after “übermensch”? I couldn't find it anywhere. Some webpages say that it's just named after the prefix „über-“.
So I presume if someone posted a comment saying “I'd love to roll him over with a steamroller” under a post about a transgender person, you would not consider that a violent threat because they are not going to actually get a steamroller?
In what world is driving a steamroller over someone not violent? How would you like it if someone made a meme about driving a steamroller over transgender people?
You know this has already turned into Reddit when people are downvoting an opinion for being unpopular.
