You're taking RMS's statement out of context. His point was that we not allow fear to overwhelm our senses so that we trade individual rights for security in police states, saying:
"Every death or injury is a sad thing, but the fact is that many happen every day, and we should not let these few upset us disproportionally more than the others. Let's make an effort not to get bent out of shape about them, so that we can resist when people try to cite them as an excuse for tyranny."
You're picking out his statement of proportionality as some sort of logical flaw in his argument, but you're completely missing the main point.
