Being a shithead can manifest itself in many ways:

If your friend says something offensive, and you don't call them out, or you only gently scold them so you can stay on good terms - you're being a shit head.

If you're criticising people behind their back, or holding your tongue in a meeting, and gossiping later - you're being a shithead.

If you're letting people off lightly because what they say doesn't personally affect you - you're being a shithead.

If you're demanding special treatment, while expecting others hold themselves to a higher standard - you're being a shithead.

If you resort to personal attacks, instead of arguing against an incorrect point - you're being a shithead.

If you hear someone state a falsehood as fact, and you don't correct them - you're being a shithead.

If you're at work and you're not agitating, and showing no concern for the well-being of others - you're being a shithead.

If you see someone harming others, while you do nothing to stop them, and do not try to reason with them - you're being a shithead.

If you do the bare minimum, with no direction, plans or goals - you're being a shithead.

If you consider yourself a veteran, better than others around you, and above menial tasks, - you're being a shithead.

If you're aware you've made a mistake, and you do nothing to correct it - you're being a shithead.

Being a shithead might keep you comfortable and safe, but you're doing harm to those around you when you engage in these behaviours.

If you're being a shithead, do not.

I try my best to uphold these principles, so yeah I guess you can say I'm pretty unpopular.

I feel like this should almost go in c/badposting haha
