Yeah, no. I don’t “fear and dislike the open exchange of ideas.” I’m tired of the (primarily online!) assumption that all opinions are equally worthy of my time, and I’m especially tired of being accused of being anti-free-speech for daring to decide who gets to occupy my relatively limited attention.
Whether free societies are durable is immaterial. They are good because they embody principles of agency and autonomy for all involved. Those principles entail both my right to ignore bad opinions, and my moral obligation to not lend credence to views that would undermine the system itself.
