Tirptiz you are close, but you are making the wrong argument here.
WHERE YOU ARE RIGHT:
Its pretty evident that human migration out of Africa 50-100k years ago resulted in genetic differences between the races, how many are genetic and how many are enviromental/cultural we will never know (even though we have some studies), because further research is impossible due to outside pressure to researchers, censorship, threats and no funding.
WHERE YOU ARE WRONG:
And for a good reason, because once you prove genetic differences tied to IQ and etc that will translate to policy changes and further discrimination and nobody wants that. Most of us want a safe society with equal rights for all people and adherence to the law, the problem is when uneducated liberal pieces of shit dont realize that equality means that if females work less hours and are less productive they will earn less and that if black people sell drugs and kill people they will get beaten up, thrown in jail and/or accidentally shot by a cop.
WHAT YOU SHOULD ARGUE:
The beef is about ethnicity/culture.
Example 1: Blacks become violent when raised in the ghettos, when they get preached into victim-hood (get it,hehe) and when no life loser liberals enable and support this behavior, but you will see that black families living in better neighbourhoods, with guidance from the parents and decent education and they thrive.
Example 2 : Whenever Albanians migrate they take up all the illegal jobs, create gangs or become employed in construction/ships at most. They have a strong culture of backwarded sauvinistic and violent beliefs and no regard for human life and those values pass around in the family. (Skend is an exception)
Example 3: If you look at muslim immigrant statistics, they score worst out of all immigrant groups in everything and everywhere from employment to crime and only a very small percentage ever assimilates into the host country culture and laws. Its probably not genetics, but the abomination of culture/ religion /political system they call islam.
Example 4: Asian immigrants in comparison score the highest in everything. Damn that could be used as an argument both ways..I believe it is the culture and not genetics, that of hard work, education, law abiding mentality and respect.
And i will close with a personal example for the liberals who think they know about the world, when the farthest they have travelled is to the local liquor shop. I live in a country in South East Asia and the country here earns so much money from tourism and in the end the infastructure is shit, pollution is high, they earn shit or if they earn they burn it god knows where. Income inequality is everywhere. The locals themselves are kind and the sweetest of people, but they cant and dont want to work and even those who do work are doing a horrible job, thats why most of the money go to Westerners including me, BECAUSE WE ACTUALLY WORK AND GIVE A DAMN and not because the evil white man is opressing them.
Does it matter in the end if they genetically have a disadvantage, if their culture is the one who pushes them to not give a fuck, be lazy and not work and pray to the gods all day and not being able to run even a convenience store?
So next time liberal lowlifes go black lives matter on you, try the culture angle.
