No, because how the fuck does a gif promote healthy discussion about anything? Then again it's neogaf, there is healthier discussion at Reddit.
Simple. Making light/fun of what was a sad/disappointing reveal to the majority helps them get into a better mood. They flush away a lot of the frustrations/anger about the event (some of which is just a kneejerk personal reaction to certain things they don't particularly like but isn't necessarily bad as a whole) by participating in/going through a topic like this.
Which then frees them up to have a more civil discussion in a thread dedicated to having a discussion. Hence, a topic like this (dedicated to gif/pics) promotes a healthy discussion.
Otherwise, some people would end up taking all of their aggression and frustration out in discussion topics themselves which would garner negative reactions (possibly on the same level) from other people that don't feel the same way leading to a worse overall actual discussion.
