The article is great. It reads full of passion yet it is very concise. I love it.
I just have one little grammatical nit-pick.
"If it sounds like I am angry. That is right. "
The use of period doesn't seem correct. "If it sounds like I am angry" is not a complete sentence.
IMHO it would read better "If this sounds angry, it's because I am angry." or "If it sounds to you like I am angry, you are right."
But, the message is clear as written and no one will stop reading because the grammar might not be 100% correct.
