Why is it one person's right to defend sexism/racism/flat earthism but it's not my right to ignore them? Are they _really_ going to give me a new perspective? Are they _really_ going to find an argument that I haven't read? I don't believe in censorship by third parties, but I believe what I put into my eyes and ears should be my choice. People can be rude, or offensive, or even abusive.As a dedicated advocate of free speech, I was initially rather put off by the right to mute. I think that if someone wants to argue anything – even that the world is flat – it does us more harm to shut them up than it does to go through the minor tedium of refuting them.
I see no ethical justification for ignoring people – but I understand that this is my standard and not necessarily everyone else’s.
