you should clarify what exactly you mean by ‘free’, cause as an outsider it just seems like you have the freedom to get indiscriminatly mowed down by high powered rifles owned by mentally ill spree shooters.

As an insider it seems like this too.

But to the guy you replied to it's most likely the freedom to have a gun which you never do those bad things with, while also plugging your ears regarding the reality that the same laws protecting your ability to have a gun and not do those bad things are enabling that endless stream of indiscriminate deaths by the folks who do those bad things.

And although I don't know him personally, he probably also deflects to mental health being the cause while continuing to vote for the party that both is responsible for our lack of mental health infrastructure and also refuses to consider restrictions on gun ownership.
