I replied to that comment as well. Affordability of housing the EU (or Japan, or China, or India, etc) isn't really that relevant to the situation in the US.
Based on your green account name, it appeared you were new to HN. I commented because the site guidelines include:
> “ Eschew flamebait. Avoid unrelated controversies and generic tangents.”
Your comment, “Don’t forget to mention they still have full health coverage in the EU.” was doing exactly what the guidelines ask us not to.
My hope was that bringing attention to this would help deflate the impending generic argument about health care and help you improve future conversations on the site.
It's not a ToS, they're guidelines. You're not legally bound, relax.
The point of these guidelines is that _generally_ most people follow them and it stops this place going to garbage like every forum before it, and allows it to stay a place for professionals to discuss topics, rather than us vs them flamebaiting and boring jokes.
You're totally welcome to go, but you're also welcome to stay. If you step back and calm down, you might find you like it here :).
