False equivalence but since this entire forum has become extremely anti-US in the last few years, there is no point for me to discuss further. I'm only responding to you because I've 'known' you for a very long time.
Anything post, discussion or notion that is even partially not 100% anti-US in nature is quickly mocked and ridiculed.
American or 'western' inferiority or lost is vehemently celebrated. I've always find this to be quite ironic considering I know for a fact that many members here reside in the US, Europe yet it as if they really hate their country of domicile.
As to your Afghanistan example again erroneous dynamics. The Soviets invaded Afghanistan with the sole purpose of occupying it. The US NEVER wanted to invade nor occupy Vietnam.
One of the primary reasons why the US pulled out was also the final realization that the S. Vietnamese leaders were totally useless and corrupted. Kennedy actually wanted to withdraw but got assassinated.
The US did NOT lose militarily. For you and others here to keep peddling that narrative is intellectually dishonest.
But hey, since I'm just one against many here who believe in the narrative that the US is just absolutely evil, while China, or in this specific case NVA, Viet Cong, HCM etc. are all pure and good and totally 'kicked US asses' with total military victories... there is no point for me to push my correction. It will fall on deaf eyes and only prolong unnecessary dissention.
You want to know why the US is being clowned on? It's the hypocrisy, simple as that.
If the west actually practice what they preach then there is nothing to clown on. Basic human right for every human beings, where Palestinians are treated as equal to the Israelis and has the same human right just for example. If this is the case I won't even joke about them would I? They'd be an inspiration right? Alas the truth is the opposite.
OTOH, if the west is honest about their imperialistic nature then there is nothing to clown on as well. "Oh we invade this country to get their stuff, we invade that country for geopolitics, we don't really care how many life's are lost or ruined...etc". If this is the case the west may invite hatred or even fear but still never ridicule.
What we have in reality is the west that is imperialistic to the core yet loves to preach like they're saint. This makes them grade A material for clowning yeah? Why would anyone not want to do so? If I met a grade A hypocrite like this in real life I'd clown on them relentlessly just for lols
But of course, if you feel so insecure about all this I suggest you go to some safe space on the internet. From what I heard r/China is especially intellectually stimulating for a mind of your caliber
