Those without civility do not deserve to be treated with civility
Years ago I took a job on an assembly line. It paid well enough - for the times, but was typical in its inherent dehumanization. Almost like being in prison (except that you get to go home each day), there were unspoken but cardinal rules that one needed to learn and, once learned strictly heeded. To step outside of those rules put you at odds with the huddling masses and could get you wound around an axle - literally.
I did OK - I made few friends but generally got along with folks. Those who were outspoken or open agitators I avoided like the plague. They typically didn't last long and were notorious for causing collateral damage.
And then there was Roland. Roland was an immigrant from some eastern european country (which one I didn't know and didn't care). Roland wasn't a big guy but he was aggressive, rude, and belligerent. Several times Roland disrespected me by cutting into line, reaching in front of me to grab what he wanted, even taking things out of my hand.
As my primary directive was to keep my job, I let it go, but it weighed on me and built compound interest with each additional slight. Finally I had enough and challenged him.
"Roland, I don't know WTF you think you're doing but if you don't stop you and me are gonna go a round or two".
"Since fighting will probably get both of us fired I intend to stomp on you until you're just a puddle of goo".
Roland just looked at me silently. After a moment he shrugged his shoulders and walked away. Another guy who was a Czech immigrant approached me and congratulated me. He told me that he had been watching the drama that had been unfolding and was wondering when (or if) I would ever defend "my honor".
"Where Roland comes from you stand your ground. Everyone treats everyone like shyt because everyone treats everyone like shyt. He didn't respect you because you didn't respect yourself - at least in his eyes. He won't diss you - unless you back down again".
I made some noise about "he better not" yada-yada. It turned out that my Czech buddy was right. Roland remained the rude prick that he was but he left me alone.
We live in a time where civility and basic courtesy are becoming a rare sight. As much as I would prefer to live in the world I grew up in, those days are gone and I am compelled to live in the real world.
