This question already has an answer here:
Is there a word for someone who tries to trip you up during conversation almost so you muddle your words and sound confused to the point where they appear to have have won a debate?
Someone who uses tactics such as these to appear that they've won a debate without actually winning based on the merit of what they have said.
They'll instead try and trip you up, or purposely respond to what you said as if it was outrageous, ridiculous or comically funny?
Their responses have no substance but their tactic is to attack what you have said, if this makes sense?
It's almost like a 'troll' but their tactics are not readily apparent to others as being 'trolling'.
Ideally you'd like to be able to say "She is such a/an X" or "She wins all her arguments through being an/a X" or "She wins her arguments by doing X" or "She only won that debate through her X tactics". Something along these lines would be helpful.
Edit: this question was marked a duplicate but the duplicate post isn't exactly the same as what I am asking. The confusion tactic is an element of their behaviour but it's also to ridicule or pick one word of what you said and attack that specific use of word, etc. All your answers have been very helpful. Thank you
