Does The Truth Change When An “Immoral” Woman Speaks It?

To decide if a woman should be allowed to speak, we excavate her morality. If she says she was raped, we talk about her multiple sexual partners and how that makes her story implausible. When she says she was harassed, we talk about the fact that she drinks alcohol. When I spoke about the army, they asked how a “modern” bisexual woman could possibly be believed? But I ask, does the truth change when an “immoral” woman speaks it?
