Start a slippery slope argument? We're way beyond started. We already have people actively seeking to tie the most mild institutions around to the most vile opinions around any way they possibly can, so that they can ban and silence anyone they disagree with. It's already happening, and only a sincere commitment to freedom of expression for all, even those we disagree with, can stop it.
Have you read the Christchurch manifesto? I have. One of his goals was accelerationism, to actively get more people banned from communication by taking extreme actions, so that they get angrier and driven to more violent actions themselves. And we're playing right into the hands of him and those who think like him by banning and censoring everything in sight.
What do you mean by "believe"? He said that one of his goals was to accelerate the conflict between two sides of the cultural divide. That's a pretty common goal of terrorism. Am I supposed to not believe him, and think he did it for some other reason?
I believe he wrote the truth about what he thinks and why he did what he did. I don't see why he would lie about that. Whether you think any of his points have any validity or agree with any of them is a whole different ballgame.
I also believe that, in a society that aspires to practice freedom of speech and freedom of expression, it is an essential skill to be able to read something you may not agree with, written by someone who took actions that you oppose, and objectively evaluate the content.
Not everyone needs to or can, but some people had better do it, if we are to have any hope of rising above the hate and division associated with these sorts of acts.
