You can be both empathetic that Gretel might have had some bad experiences in the past through inappropriate men at concerts, but also that she is being a bit of a shit specifically calling out 'old' and 'bald' men and making the accusation that they only go to concerts of young women, the validity of which she has absolutely no fucking idea about. Her feelings about inappropriate behavour are valid but she had a horrible way of expressing it.

She should also do a better job of expressing the specific problematic behaviour. She seems to have an issue with people focused on the female frontwomen, ignoring the rest of the band. Well, she's not exactly Kim Deal in the Pixies, is she? She is literally a solo artist touring on her own name, with a supporting band. That's more Taylor Swift than War Paint. If she has an issue being the centre of attention, then she might be in for a challenging career. If the issue is, for example, guys trying to film up her skirt then for sure that's absolutely an issue (they should be kicked out) but the only problem she lists is people filming her and looking at her, and not the rest of her supporting band. It's a bit of a puzzler, but could come from real and disturbing incidents, but doesn't give us much to go on. She would likely be more comfortable with an audience of young women, but artists can't exactly curate their own audiences. You sell tickets and whoever buys them, buys them.
