Before I go to bed(it's 2.30 in Germany) I'll add one thing to my previous statement:
An example: Your brother wants to start a business, but doesn't have the necessary funds. You have them, and give him a credit of $50k. You agree that it's paid back in the next 5 years with 5% interest.
But instead of getting his business going, your bother uses your money to start gambling with it and using drugs. These drugs damage him severely that he's unable to get his **** together and pay his debt back.
Now if you watch such a situation you'd prolly intervene and revoke his credit. The government can't do such a thing. It gives out credit for each and every citizen to develop skills and start his own business(as an employee, investor or whatever). Now the government can't revoke their made investments, as it can't supervise every step you make. But it has to provide each and everyone the same opportunities. That's the principle called fairness and got instituted way back then. So what does the government make to secure their investment? They put the parents name on the loan and can hold them responsible for major breach of regulations and they try to prevent each and every individual to fail and prevent such a disappointing situation(for both sides) by not allowing certain "liberties".
This may come down to seat belts in cars, declaring possession and consume of drugs as illegal(I think alcohol should be illegal too, but it has a strong lobby, same as the tobacco industry unfortunately). You can continue this list to a certain extent. In Germany for example guns are not allowed other than for purpose of hunting and sports and you actually have to be trained to use the weapons appropriately and what kind of responsibility it gives each individual.
That's a move to prevent unresponsible usage of these items and increase the security and comfort of each and every one in public.
Just think about it...
I can give you another example of your behavior of denial.
When I went to school I was a tutor for younger kids. I gave one kid living down the street lessons, who had an IQ that was way too high but lacked social skills. So the point was this kid was so bored in school, and that clever to realize the others weren't that bright. He showed everyone, including his teacher. So his mother was raising that kid alone and he didn't respond well to female authority. So that woman had the idea I assist him with his homework and teach him work attitude from a male POV a couple times a week. It wasn't that he couldn't do his homework. He simply didn't think it was worth a while. So he ran into major trouble at school with his teacher who was acting a lot like you here. She started cherry picking for mistakes, taking a narrow selected POV on everything. Best example was a math exam:
It as something like: There's a table, which has one bench attached on each side. Every bench provides space for 8 kids. How many kids can sit at the table?
The kid calculated: 8*2 = 16
The teacher marked this as a mistake. The proper train of thought was allgedly 2*8 (Two benches with 8 kids each, not 8 kids a bench times two...)
That's what I feel you're doing here. Let me tell you this. Making a valid and transparent argument on a topic is a way to show others how smart you are.
But none is always right and it really takes social intelligence to admit mistakes. That shows your bright mind even more than just creating arguments. Because you give up power in order to become more likeable and by saying: Damn I didn't think this far you give others the chance to do the same thing without it affecting the dynamic between 2 persons. That's how strangers become friends.
So I suggest you either start making good arguments for your statements or you admit you reached with your train of thought. It's not about agreeing on statements. It's about offering explanation and an argument on it in the first place.
Good night and happy discussing!
