In a genuine fight for Equality you don’t go around segregating people by identities and deeming some more deserving to fight for than others because of the identity you think that they belong to: you fight for everybody who is being treated unfairly, ideally going after that which is causing greatest pain first.
Split people by the genetics they were born with and treating them differently based on that is not the path to Equality and Fairness, it’s just a different kind of Inequality and Unfairness, so those doing such dividing and segregated treatment are either fighting for something else - say, “everybody should be free to do what they want with consenting adults”, which is fine, but at times incompatible with the core leftwing principle of “the best possible life for the greatest number”, especially when it comes to money (were the latter principle would go against the Freedom of some to accumulate as much wealth as they want), so that’s not Leftwing, that’s just Liberalism - or they’re tribalist fad followers, who don’t think when it comes to politics.
I wouldn’t be surprised if Livre end up turning out to be just as much a bunch of self-serving assholes seeking “jobs for the boys” by ridding a fashionable political strain imported from elsewhere as Portugal’s newest “Green Party” cosplayers, PAN, turned out to be.
