Re: the Barrowman situation, I think it should be pointed out that when somebody complained about his behaviour, the producers reprimanded him, so it’s not like they turned a blind eye.
Personally, I think that his antics are juvenile and disgusting, but many people who worked with him are on record saying that it’s brilliant fun. At fan conventions, he used to literally show his bare bottom to the audience and get loud cheers, and actually people would ask him specifically to do that. At least once he put a fan’s phone down his pants and took a picture, and she said it was the best day of her life or something like that, and others were quite excited, and not a single person said “eww.” Not to mention he told the story about waving his dick around several times and the audience ate it up and he got zero repercussions at the time. It’s all on youtube btw, and a lot of comments are quite positive as well.
I mean, it’s fair to blame the producers for a lot of things that went down on set, and of course Barrowman carries his own responsibility, but talking about enablers, it’s clear that a lot of people in the audience enabled his behaviour for years.
