From the perspective of a right wing "libertarian/small government" US conservative maybe. Personally I don't have much of an issue with Roosevelt besides the internment camps for Japanese US citizens ( I could maybe understand it from an irrational fear they will collaborate or for their protection but still it was still an unlawful imprisonment of US citizens as well as a propaganda victory for the modern social left).
There's no real evidence to say Roosevelt prolonged the depression and I think it would have been worse under a free market capitalist president like Hoover. For the points on guns, we can agree to disagree there, I personally would be in favour of firearm regulations but I get why US rightwingers are so steadfast on the issue. Blaming him for modern US obesity which only began taking off in the 90s is stupid imo as well as saying the reason he got involved in European affairs was because of the Germans wanting to set up puppet states in the Americas (what's the source on that as well as Britain rigging the 1940 GOP convention). Japan bombing Pearl Harbour and Germany directly declaring war has more to do with that.
The internment of Jap-Americans was a crime. It could have been somewhat justified if FDR had kept it to only 1st generation migrants who arrived in the last 10 years or something but the blanket arrest was a deliberate target by him to hype up the fear of the enemy. There are also claims of corruption regarding the forced sale of Japanese-American owned real estate but I don't know much about it.
FDR prolonged the depression and this is simple fact. The depression wouldn't have turned as bad as it did if it wasn't for the mistake made in Hoover's final days of putting tariffs to "protect" american industry in place which caused the implosion of the stock market to grow into a general depression (since it caused Europeans and other nations to cut down on buying american goods). Roosevelt's insistence on trying to control things only made things worse and instead of the natural recovery of the market as prices adjusted and trade resumed in new terms he kept trying to set the scales and prices himself which only backfired. His own secretary of treasure said it was a failure in a 1939 memo “We are spending more than we have ever spent before and it does not work. . . . I say after eight years of this Administration we have just as much unemployment as when we started. . . . And an enormous debt to boot!” You can find data and analysis on this very easy, while New Deal defenders rarely have anything other than 80yo propaganda and anecdotal evidence from pop culture.

Not gonna argue the guns then.
I blame him for the obesity because his New Deal directly led to unprofitable and unnecessary corn plantations being kept alive on government money despite there being no reason for them to keep growing corn. If he wanted to help he could have given them a deal on swapping crops, not artificially raising prices of corn to pay for it. This has been going on for 80 years now and massive fields of corn exist which produce corn that no one wants to eat. So to find something to do with all this corn that the US Government keeps cheap they turn it into High Fructose Corn Syrup and pump it into everything to trick you into thinking it is tasty and eat it, fattening your ass up.
His desire to get involved in Europe was a big and well known thing with him, and many critics of this slowly were purged from the media over the years via soft censorship since a global America meant more money. The case I mention for example is the infamous map FDR presented as "evidence" of 3rd Reich aims for the Americas which was fully fabricated by the British.
[4] The whole GOP 1940 conference thing can be found mentioned
in this book, or you can read a summary of it
on this article. But basically the British used spies and women and bribery and all sorts of cloak and dagger to move the convention into selecting literal-who Wendell Willkie (Not Alf Landon, mixed it up with 1936) who was virtually identical to FDR when it came to foreign policy as a insurance that even if the cripple lost they would be able to count on the USA to save their asses.
The Pearl Harbor attack happened because the USA had not only embargoed Japan, but also unilaterally froze jap assets in the USA and refused to negotiate for their release (meaning that literal already paid for oil and metals was kept from going to Japan, not just prohibiting trade) Which was baiting the japs into attacking because of course they wouldn't let such a move humiliate them. The fucker knew a attack was coming because the codes that Japan used had been cracked already and D.C. could have warned them with hours to spare to mobilize but they didn't.
Fuck FDR.
