It’s incredibly difficult to present a dissenting opinion on certain topics here because of the downvoting system. It used to bother me to see points go down (upon reflection the upvote/downvote system really seems to reward groupthink). I think it would better to just have upvotes.

The way the system is designed today the only people who will present a dissenting opinion on a hot topic are either very inured to social pressure, or intentionally trolling.
