depends how brainwashed the lurker's been. did you need anyone to convince you to use monero, or were you smart enough to figure it out? I am inclined to reply when I see the blatant maxi dogma to hopefully let a naive lurker know there is another viewpoint, which sets them off down their own rabbit hole - if they're smart enough, they'll figure it out. what is certainly a waste of time is trying to "win" arguments - that's just ego shit. and especially against dogmatic, closed-off minds. in that case, I only see the usefulness in exposing how close-minded they are (which likely means they have no good arguments, only emotions and insults to throw at you). for the seasoned reader, that's all they need to see to draw their own conclusions.
