Why do some people hate Sheldon?

I am a newbie to the Big Bag Theory Fandom after watching all the seasons last week. I love this show as well as all the characters. However, Sheldon holds a special place in my heart coz I can relate to him on a level I can with no other character.

I started searching and reading articles about him and realized that most people find him selfish, annoying, irritating, a-hole or Jerk. Reading all those articles, I am shocked at how they are able to jump to such conclusions.

Thankfully Some of you guys on this forum gave me hope. However, I am totally frustrated by those articles and need to vent it out somewhere. Here I go.

People judge him just based on his actions without considering his intentions.

As far as I know, there are very few instances where he was mean just to hurt others. Most of the time he doesn't even realize it. In his view, he is just stating a fact. When he says that Howard is less smart or Geology is Kardashian of Science, he truly thinks so. His intention is never to hurt Howard or anyone.

When you are an outcast and everyone leaves you alone, one usually think that either there is something wrong with them or that they are better. Eventually, this causes a superiority complex in them. I think we can all easily see how and why he thinks he is better than others.

He is a guy who values intelligence most. Hence, he is willing to be a pet of a super-intelligent alien. So naturally he thinks people that are less intelligent then him to be less than him. This is not excusable but he doesn't realize it hurts others coz he wouldn't be hurt himself if a super-intelligent alien actually treats him like that.

He is usually accused of being mean to Howard. What they fail to realize is that Howard deserves that. He replaced slides from Sheldon's lecture with pictures of nude fat women bending over. For a physicist, imagine how humiliating it would be. Anyone would not only be mean but also cruel if someone played such a prank on them. Sheldon never creates problems for Howard intentionally. He is just unintentionally mean to Howard. What Howard did is way worse. Not to mention that Sheldon gave 25% of his income from the profits of their patent to Howard's Kid. He helped Howard in case of Mars rover. Yes, he did got Howard again in trouble but anyone can see that he didn't do it intentionally. He didn't even realize until he revealed it. Howard also has done some good things for Sheldon like he took Sheldon to NASA.

Howard had Sheldon dress up as a french maid (I am not sure this is the right term) in public just cause he can. On which planet is this less mean than what Sheldon does?

Penny uses his tooth-brush to clean the sink. That is not only mean that is disgusting. The trio manipulated the Data for his research making him look like a joke.

He lent money to penny and never asked for it, gave Raj job with him when he was about to be deported, Saved Leonard, Raj and Howard from the explosion, saved Leonard from his gf who was a spy and a lot more examples.
