Why is this forum so depressing?

This may be the most active m43 forum, but it's also the most depressing. It seems 1 out of every 2 posts is someone arguing with someone else.

Just now, I saw:

- A post about m43 lenses possibly having better performance at larger apertures, an interesting topic turn into a religious debate on when/why one should stop down.

- A post, seemingly a troll post to begin with talking about how m43s are losing their size advantage and becoming same size as dslrs.

- Same posts about people either inquiring into implications of smaller sensor size getting scolded, perhaps because their intentions were misunderstood, or full on trolling posts about the so called inadequacies of 43 format.
