A better question is why just single me out for your gang mentality criticism?
I can answer this 
You actually got it wrong: I "singled you out" because you're the only one who I expect to care something about leaving accurate feedback. The other two users (roslinpl and Excimer) are tagged in deep red already. Besides, roslinpl claims "This man is a liar", which does sound like a valid reason not to trust the user. The other one (Excimer) just left troll-feedback, which any reader will instantly dismiss.

This topic isn't about you, but if you want I can share my stance in a Reputation topic.
