Maybe the fools mate opening
What's the stupidest opening?

The dumbest openings for players under 2200 is the Sicilian Defence. It is played by sheep who would rather feel content knowing that they play the same first move as Bobby fischer, meanwhile they reach positions out of the opening beyond their understanding. The 'smartest' opening is whichever opening a player understands the best, and for players under 2200, that is not the Sicilian. I genuinely feel bad when I see a weak player who is trying to improve but playing the Sicilian every game just because that's what they've seen someone do so they thought they'd copy it.

But low rated people still play the sicilian and then they lose. Actually I almost never play the sicilian with black

The person criticising the sicilian is plain out stupid. It's not even remotely as strategically complicated as 1.e5 and by your logic nobody should play chess at all as all openings are phenomonally complex. In my opinion the sicilian is a good choice as it offers entertaining games and is tactically rich which offers players the chance to enjoy chess and also to improve their tactical skills. Please reconsider before you make such an absurd comment again.

I think the stupidest opening is the dutch
I'm going to go with the Blackburn Shilling Gambit. It's basically announcing: "I don't know how to play Chess."
