I apologize that you are having a difficult time reading social cues here - it is more difficult online than in person when you can at the very least read their body language. But trust me - no one here is getting mad at you. If anything, you continuously commenting on people being mad is going to make people mad.I know I keep complaining people are getting mad at me, but they kind of are.
There's plenty of spirited discussions here. You shouldn't mistake passion or enthusiasm for anger. If you need folks to clarify, I'm sure they'd be happy to do so.
Just back up your claims with evidence and everyone will be just peachy.
