I love censorship! Without moderation once a site gets big enough it devolves into the least common denominator - spam, shit posts, abuse, and trolling. See YouTube comments for one example.
This site itself is highly censored (in the form of rules and moderation) so you aren't even upholding your own ideals by commenting here.
Not sure what you mean by highly censored, I've seen plenty of unpopular opinions on HN and people that were expressing them were never banned, in fact those users were fairly rude without being personal.
Not allowing personal attacks on HN is not just a common courtesy, it protects it users from defamation, falsehoods about their life and kidnapping of topics; those are all reasons that are perfectly compatible with freedom of speech. Detaching a tread is not censoring, I never seen it happen because of uncomfortable opinions but when it becomes hugely off topic it's clearly a valid thing to do.
I'm not the one censoring people on Hacker News, and I don't have the ability to unilaterally boycott a site and have it matter.
That's not how boycotts work.
If I were able to convince millions of people to my side, THEN I would start doing the boycott stuff.
That is the only way to have boycotts work. You have to get millions of people to be on your side and everyone has to do it all at once.
But if I had a magic wand that I could wave that would make this happen, then I'd absolutely do so.
It'd be like if I criticized a dictator and you responded by saying "well, if you hate our Supreme leader so much, then why don't you form a revolutionary movement and see how THAT works for you".
