I wouldn't expect someone as young as you to understand, you think you have a firm grasp of politics, I however have experienced all of this shit multiple times, Obama wasn't a great president but he was moving the US forward, the current gains aren't because of Trump, his policies don't even start till 2019, all the good happening is still thanks to Obama. Maybe once you have a few grey hairs and have seen how this plays out over and over you will understand. Now if you had used a valid argument such as @phyrrus9 I could understand and even debate with you. So far all you have done is shown your lack of maturity on the subject.

You could have just said "You're younger than me, therefor I do not respect you nor do I have to explain myself to you".

Much shorter and to the point.

That's technically not what he's saying.

More like "I'm older than you, therefor I have more experience, so I know more than you, and I can't explain more than I already have".
Also short and to the point, but more accurate.

I'd agree if he wasn't devaluing me for my youth as opposed to aggrandizing himself for his age. He even made a snide remark in where he refuses to provide a solid rebuttal because my argument wasn't valid. Mind you, he hasn't really proven anything to the contrary of what I said, though admittedly because he hasn't bothered to claim anything.

The point is that, even if not insulting, he's dismissing me on a ridiculously petty basis. If I persuade my grandfather of my stance, am i suddenly right because my grandfather is older? No matter how you put it, the appeal from age is just untenable. I've seen more of the world than people a decade or even more my senior, yet I must have less experience and cannot be reasoned with.

It's just frustrating. I like to argue and debate, but not with this. It's just plugging your ears and saying you're right.
