There's a bit of an echo chamber, a bit of confirmation bias, and a bit of impatient misreading in anything we write. Taking away likes won't mitigate that. It just means that people are a little less likely to post on the parts their opinions disagree (despite mostly agreeing) because of it being swamped with posts focused solely on reiteration, agreement, up simple up-arrows.
