You want a fun example of this? Look at the shooting community, specifically the “OFWG” stereotype.
This is a stereotype, not a personal or targeted attack at anyone here. If it offends you, sorry, but I’ve been to enough ranges, matches, trade shows, and classes in the past 15 years to see this is a thing.
People will make “self-defense” an entire component of their personality (or even their life’s work) while ignoring very basic realities of self-preservation.
Folks will shell out thousands of dollars for equipment and training to increase hypothetical survivability for a statistically-improbable violent attack—going so far as to avoid no-carry zones altogether and even carrying multiple guns—while eating themselves to death.
Everytime I see someone at a match, a class, open-carrying in public, or otherwise being a 2A advocate while obese, it makes me wonder: is the justification that no one has the right to kill you but you? Or is any pretext of trying to preserve your own life out the window?
That’s not to say people should avoid things they enjoy because they’re detrimental to overall health (e.g. risky hobbies like mountain biking or rock climbing, eating good food, drinking, enjoying a cigar). But, healthy moderation is a lifestyle thing. There’s a difference between an occasionally risky or unhealthful experience, done to provide short-term enjoyment, versus consigning oneself living a completely harmful and avoidable lifestyle.
