DHH or anyone else spouting opinions on social media is hardly qualified to be setting policies for countries. Social media is also hardly the place to have any sort of debate on those topics.
It tends to only be when someone is egregiously wrong or (as in the case IMO) acting in deliberate bad faith on a topic of massive public concern, like this. Because these people are a waste of psychological resources.
I totally write off proselytising antivaxxers who I think should have reason to know better, I tend to write off climate change deniers who should know better, and yes, I tend to write off educated people who mislead with statistics to create intellectual cover for xenophobic, bigoted thugs and their antisocial campaigns.
This is not an exhaustive list, but it’s a good one. Other people who get written off tend to have a nasty streak on a topic of some divisiveness. For example I am not religious but not anti-religious; I am anti being deliberately or loudly cruel, posturing or nasty about it either way. People who are like that can be like that, but they will not get to tell me about their professional interests as if their awful behaviour is just a quirk.
YMMV, but I am now middle aged and I don’t have the time for this anymore. Freedom of speech isn’t without consequences for loss of respect. If you think my position awful or lily-livered you are fully within your rights to let it colour your judgement of my opinions on technology.
