> In communism, the state owns everything.
no that would be certain currents of socialism, which is an entirely different type of marxist government. in particular leninist theory mostly bolshevism which was the leading marxist ideology around the world because of of the soviets influence.
> There are no rights as the collective is more important than the person.
authoritarian socialism, again mostly leninist streams of socialism in particular have this trait
> In socialism, they pretend to have private property but the taxes and govt spending are so high that it is only a facade of private ownership.
they don't, they have personal property, which is not just some weird socialist cope it exists in the law in quite a few capitalist states aswell. it can be kind of hard to describe the differences but basically, private property is x thing you forever have the exclusive right to unless you specifically allow. personal property is strictly what you personally posess and use, you can't just buy a house and never touch it in a socialist society, this only compasses your actual personal belongings if that makes sense. and if somebody gives you something they can't technically maintain legal ownership or any of these fuckey loopholes some companies do in modern capitalist countries. also if you're in a socialist country that runs everything taxes are then unnecassary for such purchase and jobs because the government get 100% of the procedes, generally speaking most socialist governments don't allow private enterprise to exist, but there are plenty of exceptions, including even early soviet russia.
> They pretend you have rights unless it contradicts those in power. Then, they violate the law and step on your rights anyway.
this has nothing to do with the ideology of the government and is just simple oppressive corruption, could happen in socialism capitalism fascism anything
to put extremely simplified because marxist theory and debate is a huge autistic can of worms originally written by somebody with clearly poor understanding of economics, the traditional path goes that the ideal is a communism society, which is stateless, classless, moneyless (lol), and all means of production are just treated as shared by everybody. the key point to it is voluntaryism. yes it is comically utopian. to get to that, there's traditionally a socialist intermediare, which is basically a state that can vary wildly in implementation and policies, but generally enforces these values to be ideally able to gradually change society and shift into that socialist state, a long lasting revolution. in practice these usually (but not always) tend to be rather opressive bolshevik states, and most of them completely throw out the idea of progressing past the socialist stage. again this is because of the massive influence of the soviet union. there were some legitimately decent for the people socialist states of course that didn't just let the soviets run them, but you know how america goes, they get overthrown
