Online in general? Well it starts in a more seemingly innocuous zone like r/thedonald and from there impressionable people start googling and browsing and can end up sucked into more nefarious communities which have latched onto the alt-right movement to increase their reach and make their images and messages more palatable. For every ten dipshits trolling because they want to offend or think they are "defending free speech", one might get pulled into something worse. So yes, words have an effect, shifting attitudes without restraint or nuance can have negative consequences.
The internet is becoming the defacto form of media in the world. Messages about the real world and real groups of people that aren't delivered responsibly can have actual consequences.
