If you have a Euro passport, you might as well torch your American one. There is no benefit to being identified as an American overseas when you have a European passport. In fact I would argue it is more dangerous. My family that were stuck in Kurdistan were able to avoid violence against Americans because they had Swedish passports. That little blue book is a death sentence in some places where something else wouldn't be.

"If you have a Euro passport, you might as well torch your American one."

Even if that were true, what proportion of US citizens living outside the US (the class to which my comment and the immediate parent referred) have a 'Euro passport'?

That doesn't make what I said less true. You speak to counter the claim of downsides to having an American passport, I'm providing evidence of harm to your livelihood in some parts of the world for having an American passport (versus any other kind of passport).

"You speak to counter the claim of downsides to having an American passport"

No, I spoke to counter this claim: "If you don't intend to return to the USA there are no benefits to US citizenship, only downsides."

I did not comment on the downsides. I spoke only of the benefits, which the parent comment said did not exist.

Very, very small, and only those who've lived in the EU long enough to obtain citizenship.

TIL that both UK and US passports are the most powerful passports in the world.

Only in terms of the countries you can travel to without a visa. Go just about anywhere with a Canadian passport and they'll wave you past, almost like they're annoyed you think you might be considered a security risk.

I got a 6 month visa in the UK while laid over at Heathrow in under 10 minutes. Under "Reason for your stay in the UK" I wrote "a cigarette."

Why did you need a visa to get a cigarette? Canadians don't need a visa to enter the UK for tourism/transit/business, subject to some maximum amount of time (90 days IIRC, but definitely more than enough to buy a packet of cigarettes).

I was holding a carton of Marlboro Reds purchased in Berlin, so I didn't even need to buy any. I'm fairly certain we still need a visa, but it's basically an automatic process.
