My take's basically the same as allmywhat's - I've not really followed him that closely.
Yes, "right wing", and maybe not a totally reliable journalistic source. But other voices I know better and trust seem to support him and repost his stuff (eg Glenn Greenwald, Andrew Sullivan Heather Heying) suggesting there's nothing particularly problematic.
But we've got to take what we can get. No-one else is there doing what he's doing. There are some very dangerous groups doing nasty stuff, and it's not being properly covered - cos media get attacked.
My feeling these days is "there's no smoke without fire" - if the Woke are making that much smoke about someone - they're probably on fire and saying something that you should be hearing.
And you always always have to be on the non-violent, non-hate, non-book-banning side, and in this match-up, that's Ngo.
