In what way could you possibly describe JP as "selling out"?

To the Daily Wire, evil, and Zionism; and against the disaffected male he championed for so long? Did you watch the video?

I admire much of what Peterson did, and will always defend him for his positive contributions, but he's a shadow of his former self. That was clear for quite some time, and his recent behavior isn't even novel.

Peterson is a sad joke at this point, and he's on the side of evil.
