But this has always been true; it's now just easier to be put in that state if you misread the Overton Window [0], or the Overton Window shifts faster than you can delete your posts.
Prior to social media and the massively amplified speech platforms, the consequences of out-of-window speech were limited by how big your megaphone was, and the social consequences of associating with a person with outsider views was limited by the extent that people even knew who you associated with.
In the era of hyperconnection / hyper visibility, the risk to the individual is greater in both negative effects of associating with an outsider and in being that outsider. Can you blame a company or person for not wanting to associate with someone who risks having the Eye of Sauron shift to them? If the mob came looking for the guy in the red shirt, wouldn't you look down at your own to make sure its shade was safe?
The only solution, in my view, is to not put yourself in that position to begin with. Either post without your real name (and maintain the publicly acceptable persona) or disengage entirely. All the more reason to protect anonymous platforms, ones that are libre/distributed, etc.
