As far as the inquiry goes, Reform considered crowdfunding one, then dropped the idea because if it isn't a statutory inquiry it can't compel witnesses. Lowe picked up the idea and ran with it. I'm not sure if it's achieved anything other than allowing some survivors to tell their stories, but maybe that's something.
The thing to understand about Lowe is that he's the Zarah Sultana of the right. He's not a team player and is incapable of getting along with anyone. Then, whenever he falls out with someone, he retrospectively sets up a purity test so he can say it was a matter of principle and not just a personality clash.
He's also similar to Sultana in attracting a lot of Extremely Online maniacs. More about them anon.
Lowe isn't really any kind of fascist or ethnonationalist. His own politics is almost the same as Farage's, except (1) he thinks he'd be a better leader than Farage, (2) he's got a particular bee in his bonnet about halal and kosher meat, and (3) Farage has gatekept a lot of people who genuinely are extreme out of Reform, Lowe doesn't think they should be gatekept, and predictably they have gravitated towards Lowe and formed the core of his team.
So Lowe has a choice before him, either he can be true to his own instincts and appeal to the tiny sliver of the electorate who agree with Reform policies but hate Farage; or he can surrender to his audience and be a figurehead for a movement led by idiots like Carl Benjamin, Charlie Downes and Connor Tomlinson. He'll probably do the latter, not realising that Carl and his mates are the people who destroyed Ukip in 2019, which is precisely why they are blackballed from ever joining Reform.
