Why can some black people just completely ignore racism (non-violent racism) but many others get so offended and obsessed with it?

The essence of your comment is identical to what my generation was taught as children: "Sticks and stones may break my bones, but words can never hurt me." Our culture seems to have forgotten this sage bit of wisdom, in favor of letting words hurt them.

cause everyone is different

Many people don’t understand that being emotional is energy in motion. When they feel the energy of someone’s hateful words, they lose control of their self and energy consumes them. It’s a lack of self-control. 

Also, “black” people deal with bullying and negativity only a daily basis and it’s even monetized through the media, it creates stress, ptsd, and lowers our mental health. It’s all an agenda. The sooner we realize this we can be free. 

Racism is not illegal.

yeah there are some blacks who are racist like jayz and obama. but others like larry elder and jesse lee peterson are great positive american black people. we need more people who think like you. tell people about your experience as a "red head" and bring awareness to this issue. because there are blacks who think they are the only victims and they belittle "red heads", hispanics, jews, etc. but youre right about haters hurting people and allowing them to mess up your life and about power and all. you got my two thumps up.

Another freak complaining ... no one cares

And no, even opinions are not illegal
