I'm sure you're right that the discussion here has more people on one side than the other, but if you react by lashing out in this way, you're creating the situation you're complaining about. Having skimmed this thread I'm mostly not seeing coherent arguments against the law, but rather comments like this one ("proponents of state killings"), invoking Hitler and so on—in other words, extraneous provocations that are more than enough to justify downvotes and flags.
It's pretty common for people to misattribute the reason why their comment was downvoted or flagged, and then draw wrong conclusions from that. The typical image is something like "I, the noble freethinker with principled thoughts, being suppressed by the slavish mob", when in reality the post included some tawdry swipe. The grandiose narrative always leaves out the tawdry swipe.
It makes sense that people do this—you're far from the only one—because it's extremely uncomfortable to be surrounded by hostility. Even in a rather silly place like an internet forum, it still activates survival systems in us. But since that only recharges the problem, we all need to learn how to bring more awareness to these interactions.
On issues where the community is lopsided, the person holding the contrarian position has a greater responsibility, if we're to avoid total flamewar [1]. That may not be fair, but the reasons are rooted in human nature and not going away, so we have to deal with it. If your minority view is right but you present it in a lashing-out way, the actual effect you're having is to discredit it further [2]. That helps no one.
Please don't. We're trying to avoid the online shaming/callout culture, which takes the importance of an issue as justification for going straight to personal attack. That way doesn't build community, and more importantly (for HN), it leads to much less interesting discussion, the way that scorched earth is less interesting than a thriving ecosystem.
Obviously there is room for different points of view about a topic as deep as this one.
