Really went down a rabbit's hole on this one. What a damn cat-astrophe!
Dude clearly needs to blow off some steam. Offering to meet up with someone to fight them on the pretense that they badmouthed your fiancé on an already pettyass Facebook thread, shows all signs of pent-up frustration over something else. Let's all remember this perilous post involves a pet Praying Mantis. That might be the only awesome part about this otherwise ridiculous moment of social media craziness.
As ridiculous as this is, it's kind of sweet...Either way this dude just learned his lesson the hard way. Maybe, just maybe, check that tattoo meaning the next time before you go assuming the worst, and try to make a morally righteous, misguided decision.
