The democratic party was always right wing, nothing has changed for the democrats besides shifting their voting base from the southern rurality, anti-union, and the KKK to the metropolitans. There has never been a left political entity in the USA. I find it amusing that someone actually equates any sort of change in the USA to the fucking democratic party, like holy shit how stupid can someone be if they think 'gender fluidity' is in any way, shape, or form cause or endorsed by the fucking democratic party. I'm literalling lmaoing at their life. Not only that but bundling that to the welfare state, you mean the same welfare state that doesn't meet people's housing, medical, and dietary requirements, the same welfare state that is designed to keep a surplus of labour in the USA ensuring that the job market is always smaller than available labour, keeping wages low.
