Being progressive is not just about being challenging. It is about normalizing the idea of people who aren't the majority. Whether or not Diana being bisexual would cause controversy (and I've seen enough pushback to know that it likely will), it doesn't matter because it adds to representation.
If you want Superman or Batman to be gay that badly, by all means argue for that. Don't use it to slam other representation people would want.
