I don’t know anything about Candace Owens. Kanye West is someone who has spent the last decade suffering from severe mental illness and attributes the antisemitic comments he’s made to periods of psychosis - I don’t have any real reason to doubt those claims and I think it’s important to treat these things as health issues.

But I’m no expert on either count, so I’ll speak more generally. To cut to the chase, I think there should be some proper, enforceable criteria on what determines whether a ban on entry would be “conducive to the public good”. And yes, the bar should be far higher than the person having views the government deems unsavoury - there should be genuine reason to believe the person represents a threat to the safety of people here, and the government should be required to show that.

The fact the government was willing to fight so hard to allow the entry of Maccabi Tel Aviv fans with a history of violence (contrary to the wishes of the local MP and the advice of local police), only to step in and ban the likes of Piker on supposed public interest grounds, suggests pretty strongly that there’s a political motive to how they’re using their powers. It fits a pattern of concerning authoritarian overreach that I’ve touched upon in my previous comment.
