Before Twitter conservative religious groups in the United States had and used such power to get those ideas and people they didn't like censored. This isn't a new thing brought about by Twitter, it is just more noticeable these days.
Which opens the question, is it a good thing that a tool like twitter is able to make these groups voices much more noticably amplified? It was one thing when this stuff was limited to the AM bands of radio or tabloids that everyone knew were nuts. Now we have given these people the equivalent platform of anyone else and there’s no learned cultural knowledge to ignore these voices like we’ve learned to do with AM radio crazies, since its being amplified on the same platform used by even the POTUS and all sorts of official sources of communication which acts as a signal of legitimacy for a lot of people buying into this crap.
With platforms like twitter we’ve in effect removed editors from the paper of record and let anyone contribute articles, which has turned it into a tabloid rag at best and outright propaganda at worst, but guised as where legitimate truths are found since officials and legitimate businesses and professionals have sanctified the platform with their own use.
