Half the people angry at nogs being nogs. It's not the nogs themselves, it's the attitude portrayed.
None of the other trailers had this issue though. And given articles and interviews stating R* is done with their liberal approach to games and instead adopting more progressive stances and practices with their staff and games, why are you surprised that people are looking at this and being gloomy at it given the gaming industry's track record with being progressive and shit games?
See above. A company committing to kowtowing to tumblr politics never ended up improving their products. I guarantee you no one but the most committed racists would find as much negativity if this game were still lead by the same guys who made GTA 2 - V.
Take that shit to the tourists; R* keeps saying they're a progressive company now with modern sensibilities, have made many diversity hires, and purged the toxic "frat boy" culture out of the company. FFS they bragged about it on Forbes and sites like Kotaku did victory laps around it. Look at GTA Online from 2018 onwards. If you genuinely belief there's no reason for people to be alarmed or cautious, you're being incredibly naive.
