Let's take this apart piece by piece.
1. "If one chooses to work hard and make good choices in life, America will provide that person the Avenue to success. If one chooses to embrace victim-hood mentality while not putting in the work and making poor choices in life, a positive outcome will not result."
This is a "JuSt PuLl YoUr SeLf By YoUr BoOtStRaPs" argument. First of all, many poor people work extremely hard, many more than one job, but are still poor. This means the system is failing them, not them. Also, as for most poor people, and especially black people, there are factors completely unrelated to personal choices that result in them being poor. Like how black families accrue a significantly lower amount of income as an inevitable result of centuries of slavery and discrimination, causing their child to have a poor household and a poor education, two very important factors in determining poverty. You can't dumb down poverty to just personal responsibility. Doing so doesn't solve any problems, but deflects from them.
2. "If there was systemic racism in America, Barack Obama would never have been POTUS along with a huge number of other successful black people so that kind of blows your theory out of the water, Bob."
Busting out the "iF aMeRiCa EleCtEd ObAmA, iT cAn'T bE rAcIsT!" argument. Electing Obama doesn't erase racial inequities throughout our systems in America. It doesn't erase racial disparities in the criminal justice system, policing, housing, education, income, etc. It just means, at an individual level, people are okay with voting for black person. Additionally, just because you voted for Obama, doesn't mean you can't be racist. This is like the "I hAvE a BlAcK fRiEnD" argument.
3. The vast majority of Americans judge people by their work ethic along with their behavior and character unlike leftists who judge people by their skin color.
Except employers judge blacks by their names. People with black sounding names on their resumes are less likely to get a call back than people with white sounding names.
