It's pretty simple, if you think about it. Societies losers have decided to group up and do everything they can to errode what they perceive to be the ruling ethnic group; Europeans.
They will side with literally any issue they think will hurt whites or that they think whites won't like. They aren't stupid or misguided. They know they are being hypocritical. They just don't care. They hate you and want you gone. The ends always justify the means.
