Well, it's not entirely my family; it's more just assholes I encounter in general. But my father is definitely one of those people, and as I still live with him-- I'm 18, but still in school-- I have to deal with his shit on a daily basis. I've long given up the idea of trying to change him, though, and I'm definitely planning to move out when I can, but until then, I'm stuck with him...
Well, as someone who dealt with respect issues with my father (going both directions....)
Dads will be dads. They carry a lot of baggage around that tends to land on their sons. For me, I'm pretty lazy. My dad is not. He's sort of a workaholic. So when I was 18, and living in a different house than him, he'd show up to my house at 7am and scream at me from the driveway to get out of bed so I could help him with some project he was hot to do.
This kind of interaction went back and forth between us for years until....one day in a car ride he said something, I don't even remember what, and my reaction was to utter ".....asshole."
10 minutes later we had a fist fight in the yard of my grandmother's house.
He ambushed me as we walked into the door of the house, spun me around, slammed into the door and punched me twice in the face and snarled at me that I don't dare disrespect him. I told him to go fuck himself. Then the fight moved out on to the lawn. He swung at me again, but I didn't hit him back. I did get angry though, and said something to the effect of "is that all you got old man!" Then he came at me again and I just sort of got annoyed with his flailing, shoved his ass good and hard and shouted "Get the fuck off me!"
After the awkward dinner we had immediately afterward, he and I had a (non-violent) heart to heart. Tears, hugs, the works.
We've been great friends ever since. This was probably 10 years ago.
What really tripped HIM up and made him violent is that HE thought I was disrespecting HIM, and was channeling all the years of us not being on the same page about how to do things. He essentially believed my laziness was a sign of disrespect to him, made crystal clear when I verbally disrespected him. I asked him at one point, when things were at their hottest, if we could EVER be equals and he said "No! I'm the father and you're the son and you'll never be my equal!" To which I said "that's a crock of shit. If you're being an asshole I'm going to call you an asshole. You don't get a pass on getting called out on your bullshit by me just because you're my father. I'm not 15 anymore."
So if you question where my beliefs about respect vs. violence come from, that's where.
I'm not saying get into a fist fight with your dad. But you know....sometimes this is just shit fathers and sons have to work out. My dad didn't really respect my time, what I wanted or any of that stuff. He was still trying to mold me at the age of 18. We didn't fight until I was in my 20s, when he'd long given up hope of changing who I am but had not let go of the anger and resentment that caused.
Basically, fathers can be the hardest people for sons to earn respect from because your father has high expectations of you, higher than are probably fair, because they see your life as a referendum on their parenting, their manhood, their ability to be top dog. Anything that threatens that, be it your choices in life, your attitude....can cause them to become hostile.
The watershed moment for me and my dad was me ultimately showing him I'm a man and I won't take shit from him anymore....and I didn't even have to punch him. I just weathered a couple punches without falling over and crying and then showed him that I have a line...and woe to him if he crossed it. It pretty much re-defined our relationship.
And to note...my dad isn't like, a big 'ol redneck or a real tough guy or anything....he's left leaning, thoughtful, sensitive, spiritual person. All that went out the window when dealing with me though. (My brother didn't have these conflicts with him...but he was the elder.)
So good luck. For me earning the actual respect of my father, as dramatastic as it was for me, actually changed my perspective on myself too and I learned how to be more assertive in general, and send the vibe out to strangers and others that I stand unbowed.
