He was a pretty good QB, until the opposing teams figured out his tricks and then learned to shut him down. As his career was failing, he got a SJW Girlfriend who convinced him to destroy his career with activist assholishness that lost him sponsors and politicized sports (Football). When other ignorant players followed, it hurt the viewership/attendance of the NFL. Nike felt that they had tied their brand to Kaep (his only sponsor left), so they stayed slacktivists, which might have helped them in the short term with America haters globally, but married themselves to an ideology that will be hard to extricate themselves from long term. (We'll see how this plays out). But by then Kaep went full SJW and would not back down from narcissistic self-righteousness. He was sure that he was right -- and wasn't going to let the facts, common sense, or career destruction get in the way.
Progressives seem unhappy when anyone else is happy and not waving their flags of anti-patriotism. They see some injustice in the world (real or imagined) and they feel compelled to lecture and spoil anyone else's good time. Nothing demonstrates this more than the recent politicization of sports -- with the completely expected consequences that this alienates enough of the audience, to ruin it for everyone.
Nike made some Patriotic Americana Shoes, with the Betsy Ross flag. Colin Kaepernick whined to them that since the flag came from the era of slavery it hurt his black-half's feelings as it was a symbol of the White Patriarchy (or White Supremacy), which explains why Obama flew it at his 2012 inauguration. Nike took the Anti-American position (again), and pulled the shoes. Kaepernick had previously said he was protesting police brutality, not the Flag itself... but this proved otherwise: it's symbols of America that he (and Nike by proxy) hate. Arizona and New Mexico pulled tax incentives for Nike manufacturing in their state, while the Governor of the People's Republic of California, Gavin Newsom (D), and other Democrats, jumped in, and said they thought Nike was being American by being anti-Flag. Trump Jr. jumped in by retweeting a shoe more likely to fit where their loyalties lie (a soviet style shoe).
Context: Colin protested the Betsy Ross flag because there was slavery. Betsy Ross was a Quaker. Quakers were ardent abolitionists who opposed slavery and helped with the Underground Railroad. She ran her own small business and never had slaves. She is being lambasted by Nike and Colin Kaepernick who both profiteer from a near-slave labor force of 85% female Vietnamese who are paid about $1.00 per hour for their 48 hour work week. This leaves the question, are they ignorant or hypocritical virtue signaling elitists?
Woke Corporate Slacktivism is the idea that corporations should stop trying to maximize shareholder value by meeting their customers needs, but start becoming political/religious organizations that preach their agendas to others. It seems to fail more than it works, because most people are wise enough to recognize that they're insincere. And even those gullible enough to believe otherwise just find some other hypocrisy by the company to feed their need for moral outrage. So their short term allies will always turn on them, and they alienate everyone else.
This section is not comprehensive analysis of all the complexities of a persons life, but more the points most often brushed over (the counter-balances to the myth-making/propaganda). So these are not meant to be read in isolation, but as complimentary aspects on people (or issues about them) that are on the road that's less travelled.
