The problem with socialism has never been the theoretical ideology. Nobody is arguing that people shouldn't have food, education or healthcare.

The problem with socialism is implementation. When the ideology is faced against economic reality it simply doesn't work. It's impossible to give value and resources to someone without taking them from someone else. You can't create food or housing out of thin air. It will always require some amount of time and energy from someone else.

In theory, if some people in society are willing to give up some of their time, energy and resources to provide for others then you might have a form of socialism that works. People like this do exist, mostly at the family level but it gets much more difficult at the society level.

The only way humans have found to implement socialism at the society level is through the threat of violence and theft. Mechanically taxation is no different from theft because you don't have a choice regardless of how you feel about it. Your value is taken from you weather you like it or not. It's no different now than it was when the kings mean rode up to you on a horse pointing a sword in your face.

But here's the worst part. I would say most people are okay with the idea of paying some amount to provide for others. That's what they think their taxes are doing. Unfortunately, that's not really how it works. Most of your taxes are not going to the people who need it most. Corruption, incompetence, bureaucracy and inflation have made it so that more than half of the time and energy you spend goes to people who don't deserve it.

In short, it does not matter if you believe in socialism if there's no way to actually implement it fairly.
