ELI5: Anti-French sentiment in the United States.

I don't understand it.  What I'm referring to is the comments from conservative types like, "the french are a bunch of wussies!" or referencing how they would be speaking German if it wasn't for us in WWII.  What happened that would give some people these ideas?

(I hope you know what I'm referring to because I can't understand the sentiment and it seems to revolve around those two themes)

Edit: I don't mean the 'freedom fries' and other silly jokes, I mean actual disdain that I have encountered from conservatives mostly in my own family who think the French dropped the ball in WWII and took an apparently ungrateful stance towards the US for their assistance (which I don't know how true that is among the citizenry even if DeGaulle wasn't grateful but I think that may be for reasons to encourage his countrymen more than a slap to the face of America.) Or if the citizens of France were ungrateful, I do not know why.

The name calling is used to silence and nullify their arguments.

In WW2 France made a lot of poor decisions when it came to defense. The Germans broke through and stormed Paris, which was given up without a fight.

The reality of the situation is more complex, but the obviously childish sentiment is fun to join in on, and any objection merely adds to the amusement.

The reality is that France didn't agree with America's illegal invasions of Iraq and Afghanistan. Moreover they were vocal about it.  Unfortunately time has shown France's reticence to be entirely valid and America's taxpayers have paid dearly for their mistake.

This makes the namecalling even more satisfying.
