I've always been of the opinion that fans shouldn't shield their faves' mistakes and be willing to acknowledge when they're in the wrong. At the same time, it's not right to cancel someone and everyone deserves a second chance. Otherwise it just means that we're coming from a place of moral superiority and rather than wanting the person to change, we simply wanted something to hold over them.
Imo Irene made a mistake, and sure she might have been forced to apologize in the first place, but this apology does sound sincere. If you are never called out on your behavior, it becomes normalized, until you someday realize it too late. It does look like she's genuinely reflecting and the stylist has accepted the apology long back.
Here's hoping for both Irene and the rest of RV to resume full group activities and also that fans don't harass the stylist over it. Some maturity from both defenders and accusers of Irene would be the ideal outcome.
