Misogynistic lyrics?! Hell no ... so says Logan Paul, who's firing back at the Flobots after the band blasted his "Handlebars" remix as dumb and sexist.

BACKSTORY: Paul released "No Handlebars" back in November and it blew up -- more than 28 million views on YouTube. The whole song contains nonsensical lyrics about riding a chick like a bike.

Flobots founder Jonny 5 HATED the remix and blasted him in a response diss track -- claiming he disrespected the original version ... and clowned Logan by saying, "Looks like Donald Trump's kid has arrived."

He also called Logan young, dumb and attention-starved -- pretty aggressive stuff.

So, when we saw Logan at LAX, we had to ask what he thought of the Flobots diss -- and he had some shade of his own to throw ... playing the "Who are they?" card.

He also argued that he's not a misogynist -- he's just an artist trying to do creative things ... and doesn't really know what "riding your girl with no handlebars" really means.
