Your maths example is incontestably true so no-one would waste time debating it. Claiming js is essential to all modern browsing is not true and I am contesting it because in practice its use opens up bloody great security holes. And you are still not addressing my obvious and relevant point, that not using js closes those holes. Stop downvoting and explain why you think compromising browsing safety is your right.
