That's toxic? First, sounds very straw-man. Second, okay, someone said they think something's unethical. Maybe it is? Maybe they have a point they didn't articulate well? Maybe they're straight-up wrong! If you're arguing for free speech, then you're arguing in favor of people being vocally critical of ideas you hold dear. Hiding under the pillow fort of "California is so intolerant" makes it seem like what you're actually complaining about is people disagreeing with you.
